python-tabulate |
|
=============== |
|
|
|
Pretty-print tabular data in Python, a library and a command-line |
|
utility. |
|
|
|
The main use cases of the library are: |
|
|
|
- printing small tables without hassle: just one function call, |
|
formatting is guided by the data itself |
|
- authoring tabular data for lightweight plain-text markup: multiple |
|
output formats suitable for further editing or transformation |
|
- readable presentation of mixed textual and numeric data: smart |
|
column alignment, configurable number formatting, alignment by a |
|
decimal point |
|
|
|
Installation |
|
------------ |
|
|
|
To install the Python library and the command line utility, run: |
|
|
|
```shell |
|
pip install tabulate |
|
``` |
|
|
|
The command line utility will be installed as `tabulate` to `bin` on |
|
Linux (e.g. `/usr/bin`); or as `tabulate.exe` to `Scripts` in your |
|
Python installation on Windows (e.g. `C:\Python39\Scripts\tabulate.exe`). |
|
|
|
You may consider installing the library only for the current user: |
|
|
|
```shell |
|
pip install tabulate --user |
|
``` |
|
|
|
In this case the command line utility will be installed to |
|
`~/.local/bin/tabulate` on Linux and to |
|
`%APPDATA%\Python\Scripts\tabulate.exe` on Windows. |
|
|
|
To install just the library on Unix-like operating systems: |
|
|
|
```shell |
|
TABULATE_INSTALL=lib-only pip install tabulate |
|
``` |
|
|
|
On Windows: |
|
|
|
```shell |
|
set TABULATE_INSTALL=lib-only |
|
pip install tabulate |
|
``` |
|

|
Library usage |
|
------------- |
|
|
|
The module provides just one function, `tabulate`, which takes a list of |
|
lists or another tabular data type as the first argument, and outputs a |
|
nicely formatted plain-text table: |
|
|
|
```pycon |
|
>>> from tabulate import tabulate |
|
|
|
>>> table = [["Sun",696000,1989100000],["Earth",6371,5973.6], |
|
... ["Moon",1737,73.5],["Mars",3390,641.85]] |
|
>>> print(tabulate(table)) |
|
----- ------ ------------- |
|
Sun 696000 1.9891e+09 |
|
Earth 6371 5973.6 |
|
Moon 1737 73.5 |
|
Mars 3390 641.85 |
|
----- ------ ------------- |
|
``` |
|
|
|
The following tabular data types are supported: |
|
|
|
- list of lists or another iterable of iterables |
|
- list or another iterable of dicts (keys as columns) |
|
- dict of iterables (keys as columns) |
|
- list of dataclasses (Python 3.7+ only, field names as columns) |
|
- two-dimensional NumPy array |
|
- NumPy record arrays (names as columns) |
|
- pandas.DataFrame |
|
|
|
Tabulate is a Python3 library. |
|
|
|
### Headers |
|
|
|
The second optional argument named `headers` defines a list of column |
|
headers to be used: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers=["Planet","R (km)", "mass (x 10^29 kg)"])) |
|
Planet R (km) mass (x 10^29 kg) |
|
-------- -------- ------------------- |
|
Sun 696000 1.9891e+09 |
|
Earth 6371 5973.6 |
|
Moon 1737 73.5 |
|
Mars 3390 641.85 |
|
``` |
|
|
|
If `headers="firstrow"`, then the first row of data is used: |
|
|
|
```pycon |
|
>>> print(tabulate([["Name","Age"],["Alice",24],["Bob",19]], |
|
... headers="firstrow")) |
|
Name Age |
|
------ ----- |
|
Alice 24 |
|
Bob 19 |
|
``` |
|
|
|
If `headers="keys"`, then the keys of a dictionary/dataframe, or column |
|
indices are used. It also works for NumPy record arrays and lists of |
|
dictionaries or named tuples: |
|
|
|
```pycon |
|
>>> print(tabulate({"Name": ["Alice", "Bob"], |
|
... "Age": [24, 19]}, headers="keys")) |
|
Age Name |
|
----- ------ |
|
24 Alice |
|
19 Bob |
|
``` |
|
|
|
### Row Indices |
|
|
|
By default, only pandas.DataFrame tables have an additional column |
|
called row index. To add a similar column to any other type of table, |
|
pass `showindex="always"` or `showindex=True` argument to `tabulate()`. |
|
To suppress row indices for all types of data, pass `showindex="never"` |
|
or `showindex=False`. To add a custom row index column, pass |
|
`showindex=rowIDs`, where `rowIDs` is some iterable: |
|
|
|
```pycon |
|
>>> print(tabulate([["F",24],["M",19]], showindex="always")) |
|
- - -- |
|
0 F 24 |
|
1 M 19 |
|
- - -- |
|
``` |
|
|
|
### Table format |
|
|
|
There is more than one way to format a table in plain text. The third |
|
optional argument named `tablefmt` defines how the table is formatted. |
|
|
|
Supported table formats are: |
|
|
|
- "plain" |
|
- "simple" |
|
- "github" |
|
- "grid" |
|
- "simple\_grid" |
|
- "rounded\_grid" |
|
- "heavy\_grid" |
|
- "mixed\_grid" |
|
- "double\_grid" |
|
- "fancy\_grid" |
|
- "outline" |
|
- "simple\_outline" |
|
- "rounded\_outline" |
|
- "heavy\_outline" |
|
- "mixed\_outline" |
|
- "double\_outline" |
|
- "fancy\_outline" |
|
- "pipe" |
|
- "orgtbl" |
|
- "asciidoc" |
|
- "jira" |
|
- "presto" |
|
- "pretty" |
|
- "psql" |
|
- "rst" |
|
- "mediawiki" |
|
- "moinmoin" |
|
- "youtrack" |
|
- "html" |
|
- "unsafehtml" |
|
- "latex" |
|
- "latex\_raw" |
|
- "latex\_booktabs" |
|
- "latex\_longtable" |
|
- "textile" |
|
- "tsv" |
|
|
|
`plain` tables do not use any pseudo-graphics to draw lines: |
|
|
|
```pycon |
|
>>> table = [["spam",42],["eggs",451],["bacon",0]] |
|
>>> headers = ["item", "qty"] |
|
>>> print(tabulate(table, headers, tablefmt="plain")) |
|
item qty |
|
spam 42 |
|
eggs 451 |
|
bacon 0 |
|
``` |
|
|
|
`simple` is the default format (the default may change in future |
|
versions). It corresponds to `simple_tables` in [Pandoc Markdown |
|
extensions](http://johnmacfarlane.net/pandoc/README.html#tables): |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="simple")) |
|
item qty |
|
------ ----- |
|
spam 42 |
|
eggs 451 |
|
bacon 0 |
|
``` |
|
|
|
`github` follows the conventions of GitHub flavored Markdown. It |
|
corresponds to the `pipe` format without alignment colons: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="github")) |
|
| item | qty | |
|
|--------|-------| |
|
| spam | 42 | |
|
| eggs | 451 | |
|
| bacon | 0 | |
|
``` |
|
|
|
`grid` is like tables formatted by Emacs' |
|
[table.el](http://table.sourceforge.net/) package. It corresponds to |
|
`grid_tables` in Pandoc Markdown extensions: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="grid")) |
|
+--------+-------+ |
|
| item | qty | |
|
+========+=======+ |
|
| spam | 42 | |
|
+--------+-------+ |
|
| eggs | 451 | |
|
+--------+-------+ |
|
| bacon | 0 | |
|
+--------+-------+ |
|
``` |
|
|
|
`simple_grid` draws a grid using single-line box-drawing characters: |
|
|
|

|
`pipe` follows the conventions of [PHP Markdown |
|
Extra](http://michelf.ca/projects/php-markdown/extra/#table) extension. |
|
It corresponds to `pipe_tables` in Pandoc. This format uses colons to |
|
indicate column alignment: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="pipe")) |
|
| item | qty | |
|

|
format: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="asciidoc")) |

``` |
|
|
|
`orgtbl` follows the conventions of Emacs |
|
[org-mode](http://orgmode.org/manual/Tables.html), and is editable also |
|
in the minor orgtbl-mode. Hence its name: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="orgtbl")) |
|
| item | qty | |
|
|--------+-------| |
|
| spam | 42 | |
|
| eggs | 451 | |
|
| bacon | 0 | |
|
``` |
|
|
|
`jira` follows the conventions of Atlassian Jira markup language: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="jira")) |
|
|| item || qty || |
|
| spam | 42 | |
|
| eggs | 451 | |
|
| bacon | 0 | |
|
``` |
|
|
|
`rst` formats data like a simple table of the |
|
[reStructuredText](http://docutils.sourceforge.net/docs/user/rst/quickref.html#tables) |
|
format: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="rst")) |
|
====== ===== |
|
item qty |
|
====== ===== |
|
spam 42 |
|
eggs 451 |
|
bacon 0 |
|
====== ===== |
|
``` |
|
|
|
`mediawiki` format produces a table markup used in |
|
[Wikipedia](http://www.mediawiki.org/wiki/Help:Tables) and on other |
|
MediaWiki-based sites: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="mediawiki")) |
|
{| class="wikitable" style="text-align: left;" |
|
|+ <!-- caption --> |
|
|- |
|
! item !! align="right"| qty |
|
|- |
|
| spam || align="right"| 42 |
|
|- |
|
| eggs || align="right"| 451 |

|
[MoinMoin](https://moinmo.in/) wikis: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="moinmoin")) |
|
|| ''' item ''' || ''' quantity ''' || |
|
|| spam || 41.999 || |
|
|| eggs || 451 || |
|
|| bacon || || |
|
``` |
|
|
|
`youtrack` format produces a table markup used in Youtrack tickets: |
|
|
|

|
>>> print(tabulate(table, headers, tablefmt="youtrack")) |
|
|| item || quantity || |
|
| spam | 41.999 | |
|
| eggs | 451 | |
|
| bacon | | |
|
``` |
|
|
|
`textile` format produces a table markup used in |
|
[Textile](http://redcloth.org/hobix.com/textile/) format: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="textile")) |
|
|_. item |_. qty | |
|
|<. spam |>. 42 | |
|
|<. eggs |>. 451 | |
|
|<. bacon |>. 0 | |
|
``` |
|
|
|
`html` produces standard HTML markup as an html.escape'd str |
|
with a ._repr_html_ method so that Jupyter Lab and Notebook display the HTML |
|
and a .str property so that the raw HTML remains accessible. |
|
`unsafehtml` table format can be used if an unescaped HTML is required: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="html")) |
|
<table> |
|
<tbody> |
|
<tr><th>item </th><th style="text-align: right;"> qty</th></tr> |
|
<tr><td>spam </td><td style="text-align: right;"> 42</td></tr> |
|
<tr><td>eggs </td><td style="text-align: right;"> 451</td></tr> |
|
<tr><td>bacon </td><td style="text-align: right;"> 0</td></tr> |
|
</tbody> |
|
</table> |
|
``` |
|
|
|
`latex` format creates a `tabular` environment for LaTeX markup, |
|
replacing special characters like `_` or `\` to their LaTeX |
|
correspondents: |
|
|
|
```pycon |
|
>>> print(tabulate(table, headers, tablefmt="latex")) |
|
\begin{tabular}{lr} |
|
\hline |
|
item & qty \\ |
|
\hline |
|
spam & 42 \\ |
|
eggs & 451 \\ |
|
bacon & 0 \\ |
|
\hline |
|
\end{tabular} |
|
``` |
|
|
|
`latex_raw` behaves like `latex` but does not escape LaTeX commands and |
|
special characters. |
|
|
|
`latex_booktabs` creates a `tabular` environment for LaTeX markup using |
|
spacing and style from the `booktabs` package. |
|
|
|
`latex_longtable` creates a table that can stretch along multiple pages, |
|
using the `longtable` package. |
|
|
|
### Column alignment |
|
|
|
`tabulate` is smart about column alignment. It detects columns which |
|
contain only numbers, and aligns them by a decimal point (or flushes |
|
them to the right if they appear to be integers). Text columns are |
|
flushed to the left. |
|
|
|
You can override the default alignment with `numalign` and `stralign` |
|
named arguments. Possible column alignments are: `right`, `center`, |
|
`left`, `decimal` (only for numbers), and `None` (to disable alignment). |
|
|
|
Aligning by a decimal point works best when you need to compare numbers |
|
at a glance: |
|
|
|
```pycon |
|
>>> print(tabulate([[1.2345],[123.45],[12.345],[12345],[1234.5]])) |
|
---------- |
|
1.2345 |
|
123.45 |
|
12.345 |
|
12345 |
|
1234.5 |
|
---------- |
|
``` |
|
|
|
Compare this with a more common right alignment: |
|
|
|
```pycon |
|
>>> print(tabulate([[1.2345],[123.45],[12.345],[12345],[1234.5]], numalign="right")) |
|
------ |
|
1.2345 |
|
123.45 |
|
12.345 |
|
12345 |
|
1234.5 |
|
------ |
|
``` |
|
|
|
For `tabulate`, anything which can be parsed as a number is a number. |
|
Even numbers represented as strings are aligned properly. This feature |
|
comes in handy when reading a mixed table of text and numbers from a |
|
file: |
|
|
|
```pycon |
|
>>> import csv ; from StringIO import StringIO |
|
>>> table = list(csv.reader(StringIO("spam, 42\neggs, 451\n"))) |
|
>>> table |
|
[['spam', ' 42'], ['eggs', ' 451']] |
|
>>> print(tabulate(table)) |
|
---- ---- |
|
spam 42 |
|
eggs 451 |
|
---- ---- |
|
``` |
|
|
|
To disable this feature use `disable_numparse=True`. |
|
|
|
```pycon |
|
>>> print(tabulate.tabulate([["Ver1", "18.0"], ["Ver2","19.2"]], tablefmt="simple", disable_numparse=True)) |
|
---- ---- |
|
Ver1 18.0 |
|
Ver2 19.2 |
|
---- ---- |
|
``` |
|
|
|
### Custom column alignment |
|
|
|
`tabulate` allows a custom column alignment to override the above. The |
|
`colalign` argument can be a list or a tuple of `stralign` named |
|
arguments. Possible column alignments are: `right`, `center`, `left`, |
|
`decimal` (only for numbers), and `None` (to disable alignment). |
|
Omitting an alignment uses the default. For example: |
|
|
|
```pycon |
|
>>> print(tabulate([["one", "two"], ["three", "four"]], colalign=("right",)) |
|
----- ---- |
|
one two |
|
three four |
|
----- ---- |
|
``` |
|
|
|
### Number formatting |
|
|
|
`tabulate` allows to define custom number formatting applied to all |
|
columns of decimal numbers. Use `floatfmt` named argument: |
|
|
|
```pycon |
|
>>> print(tabulate([["pi",3.141593],["e",2.718282]], floatfmt=".4f")) |
|
-- ------ |
|
pi 3.1416 |
|
e 2.7183 |
|
-- ------ |
|
``` |
|
|
|
`floatfmt` argument can be a list or a tuple of format strings, one per |
|
column, in which case every column may have different number formatting: |
|
|
|
```pycon |
|
>>> print(tabulate([[0.12345, 0.12345, 0.12345]], floatfmt=(".1f", ".3f"))) |
|
--- ----- ------- |
|
0.1 0.123 0.12345 |
|
--- ----- ------- |
|
``` |
|
|
|
`intfmt` works similarly for integers |
|
|
|
>>> print(tabulate([["a",1000],["b",90000]], intfmt=",")) |
|
- ------ |
|
a 1,000 |
|
b 90,000 |
|
- ------ |
|
|
|
### Text formatting |
|
|
|
By default, `tabulate` removes leading and trailing whitespace from text |
|
columns. To disable whitespace removal, set the global module-level flag |
|
`PRESERVE_WHITESPACE`: |
|
|
|
```python |
|
import tabulate |
|
tabulate.PRESERVE_WHITESPACE = True |
|
``` |
|
|
|
### Wide (fullwidth CJK) symbols |
|
|
|
To properly align tables which contain wide characters (typically |
|
fullwidth glyphs from Chinese, Japanese or Korean languages), the user |
|
should install `wcwidth` library. To install it together with |
|
`tabulate`: |
|
|
|
```shell |
|
pip install tabulate[widechars] |
|
``` |
|
|
|
Wide character support is enabled automatically if `wcwidth` library is |
|
already installed. To disable wide characters support without |
|
uninstalling `wcwidth`, set the global module-level flag |
|
`WIDE_CHARS_MODE`: |
|
|
|
```python |
|
import tabulate |
|
tabulate.WIDE_CHARS_MODE = False |
|
``` |
|
|
|
### Multiline cells |
|
|
|
Most table formats support multiline cell text (text containing newline |
|
characters). The newline characters are honored as line break |
|
characters. |
|
|
|
Multiline cells are supported for data rows and for header rows. |
|
|
|
Further automatic line breaks are not inserted. Of course, some output |
|
formats such as latex or html handle automatic formatting of the cell |
|
content on their own, but for those that don't, the newline characters |
|
in the input cell text are the only means to break a line in cell text. |
|
|
|
Note that some output formats (e.g. simple, or plain) do not represent |
|
row delimiters, so that the representation of multiline cells in such |
|
formats may be ambiguous to the reader. |
|
|
|
The following examples of formatted output use the following table with |
|
a multiline cell, and headers with a multiline cell: |
|
|
|
```pycon |
|
>>> table = [["eggs",451],["more\nspam",42]] |
|
>>> headers = ["item\nname", "qty"] |
|
``` |
|
|
|
`plain` tables: |
|
|
|

|
>>> print(tabulate(table, headers, tablefmt="plain")) |
|

|
more 42 |
|

|
``` |
|
|
|

|
name |
|
====== ===== |
|
eggs 451 |
|
more 42 |
|
spam |
|
====== ===== |
|
``` |
|
|
|
Multiline cells are not well-supported for the other table formats. |
|
|
|
### Automating Multilines |
|
While tabulate supports data passed in with multilines entries explicitly provided, |
|
it also provides some support to help manage this work internally. |
|
|
|
The `maxcolwidths` argument is a list where each entry specifies the max width for |
|
it's respective column. Any cell that will exceed this will automatically wrap the content. |
|
To assign the same max width for all columns, a singular int scaler can be used. |
|
|
|
Use `None` for any columns where an explicit maximum does not need to be provided, |
|
and thus no automate multiline wrapping will take place. |
|
|
|
The wrapping uses the python standard [textwrap.wrap](https://docs.python.org/3/library/textwrap.html#textwrap.wrap) |
|
function with default parameters - aside from width. |
|
|
|
This example demonstrates usage of automatic multiline wrapping, though typically |
|
the lines being wrapped would probably be significantly longer than this. |
|
|
|
```pycon |
|
>>> print(tabulate([["John Smith", "Middle Manager"]], headers=["Name", "Title"], tablefmt="grid", maxcolwidths=[None, 8])) |
|
+------------+---------+ |
|
| Name | Title | |
|
+============+=========+ |
|
| John Smith | Middle | |
|
| | Manager | |
|
+------------+---------+ |
|
``` |
|
|
|
### Adding Separating lines |
|
One might want to add one or more separating lines to highlight different sections in a table. |
|
|
|
The separating lines will be of the same type as the one defined by the specified formatter as either the |
|
linebetweenrows, linebelowheader, linebelow, lineabove or just a simple empty line when none is defined for the formatter |
|
|
|
|
|
>>> from tabulate import tabulate, SEPARATING_LINE |
|
|
|
table = [["Earth",6371], |
|
["Mars",3390], |
|
SEPARATING_LINE, |
|
["Moon",1737]] |
|
print(tabulate(table, tablefmt="simple")) |
|
----- ---- |
|
Earth 6371 |
|
Mars 3390 |
|
----- ---- |
|
Moon 1737 |
|
----- ---- |
|
|
|
### ANSI support |
|
ANSI escape codes are non-printable byte sequences usually used for terminal operations like setting |
|
color output or modifying cursor positions. Because multi-byte ANSI sequences are inherently non-printable, |
|
they can still introduce unwanted extra length to strings. For example: |
|
|
|
>>> len('\033[31mthis text is red\033[0m') # printable length is 16 |
|
25 |
|
|
|
To deal with this, string lengths are calculated after first removing all ANSI escape sequences. This ensures |
|
that the actual printable length is used for column widths, rather than the byte length. In the final, printable |
|
table, however, ANSI escape sequences are not removed so the original styling is preserved. |
|
|
|
Some terminals support a special grouping of ANSI escape sequences that are intended to display hyperlinks |
|
much in the same way they are shown in browsers. These are handled just as mentioned before: non-printable |
|
ANSI escape sequences are removed prior to string length calculation. The only diifference with escaped |
|
hyperlinks is that column width will be based on the length of the URL _text_ rather than the URL |
|
itself (terminals would show this text). For example: |
|
|
|
>>> len('\x1b]8;;https://example.com\x1b\\example\x1b]8;;\x1b\\') # display length is 7, showing 'example' |
|
45 |
|
|
|
|
|
Usage of the command line utility |
|
--------------------------------- |
|
|
|
Usage: tabulate [options] [FILE ...] |
|
|
|
FILE a filename of the file with tabular data; |
|
if "-" or missing, read data from stdin. |
|
|
|
Options: |
|
|
|
-h, --help show this message |
|
-1, --header use the first row of data as a table header |
|
-o FILE, --output FILE print table to FILE (default: stdout) |
|
-s REGEXP, --sep REGEXP use a custom column separator (default: whitespace) |
|
-F FPFMT, --float FPFMT floating point number format (default: g) |
|
-I INTFMT, --int INTFMT integer point number format (default: "") |
|
-f FMT, --format FMT set output table format; supported formats: |
|
plain, simple, github, grid, fancy_grid, pipe, |
|
orgtbl, rst, mediawiki, html, latex, latex_raw, |
|
latex_booktabs, latex_longtable, tsv |
|
(default: simple) |
|
|
|
Performance considerations |
|
-------------------------- |
|
|
|
Such features as decimal point alignment and trying to parse everything |
|
as a number imply that `tabulate`: |
|
|
|
- has to "guess" how to print a particular tabular data type |
|
- needs to keep the entire table in-memory |
|
- has to "transpose" the table twice |
|
- does much more work than it may appear |
|
|
|
It may not be suitable for serializing really big tables (but who's |
|
going to do that, anyway?) or printing tables in performance sensitive |
|
applications. `tabulate` is about two orders of magnitude slower than |
|
simply joining lists of values with a tab, comma, or other separator. |
|
|
|
At the same time, `tabulate` is comparable to other table |
|
pretty-printers. Given a 10x10 table (a list of lists) of mixed text and |
|
numeric data, `tabulate` appears to be slower than `asciitable`, and |
|
faster than `PrettyTable` and `texttable` The following mini-benchmark |
|
was run in Python 3.9.13 on Windows 10: |
|
|
|
================================= ========== =========== |
|
Table formatter time, μs rel. time |
|
================================= ========== =========== |
|
csv to StringIO 12.5 1.0 |
|
join with tabs and newlines 14.6 1.2 |
|
asciitable (0.8.0) 192.0 15.4 |
|
tabulate (0.9.0) 483.5 38.7 |
|
tabulate (0.9.0, WIDE_CHARS_MODE) 637.6 51.1 |
|
PrettyTable (3.4.1) 1080.6 86.6 |
|
texttable (1.6.4) 1390.3 111.4 |
|

How to contribute |
|
----------------- |
|
|
|
Contributions should include tests and an explanation for the changes |
|
they propose. Documentation (examples, docstrings, README.md) should be |
|
updated accordingly. |
|
|
|
This project uses [pytest](https://docs.pytest.org/) testing |
|
framework and [tox](https://tox.readthedocs.io/) to automate testing in |
|
different environments. Add tests to one of the files in the `test/` |
|
folder. |
|
|
|
To run tests on all supported Python versions, make sure all Python |
|
interpreters, `pytest` and `tox` are installed, then run `tox` in the root |
|
of the project source tree. |
|
|
|
On Linux `tox` expects to find executables like `python3.7`, `python3.8` etc. |
|
On Windows it looks for `C:\Python37\python.exe`, `C:\Python38\python.exe` etc. respectively. |
|
|
|
One way to install all the required versions of the Python interpreter is to use [pyenv](https://github.com/pyenv/pyenv). |
|
All versions can then be easily installed with something like: |
|
|
|
pyenv install 3.7.12 |
|
pyenv install 3.8.12 |
|
... |
|
|
|
Don't forget to change your `PATH` so that `tox` knows how to find all the installed versions. Something like |
|
|
|
export PATH="${PATH}:${HOME}/.pyenv/shims" |
|
|
|
To test only some Python environments, use `-e` option. For example, to |
|
test only against Python 3.7 and Python 3.10, run: |
|
|
|
```shell |
|
tox -e py37,py310 |
|
``` |
|
|
|
in the root of the project source tree. |
|
|
|
To enable NumPy and Pandas tests, run: |
|
|
|
```shell |
|
tox -e py37-extra,py310-extra |
|
``` |
|
|
|
(this may take a long time the first time, because NumPy and Pandas will |
|
have to be installed in the new virtual environments) |
|
|
|
To fix code formatting: |
|
|
|
```shell |
|
tox -e lint |
|
``` |
|
|
|
See `tox.ini` file to learn how to use to test |
|
individual Python versions. |
