+To do so, you have been given access to a list of tools: these tools are Python functions which you can call with code. Always only call ONE per code blob you write and always print out the result.
 To solve the task, you must plan forward to proceed in a series of steps, in a cycle of Thought, Code, and Observation sequences. Again always only call one function per iteration and always print out the result.
-
 At each step, in the 'Thought:' sequence, you should first explain your reasoning towards solving the task and the tools that you want to use. 
 Then in the Code sequence you should write the code in simple Python. The code sequence must be opened with '<code>', and closed with '</code>' and should consist of ONE function call followed by a print statement that prints the result of the function call.
-During each intermediate step, you wil use 'print()' to save whatever important information you will then need.
+During each intermediate step, when you use 'print()' it will save whatever important information you will then need.
