streamlit
# 🎨 Build interactive web apps: st.title("Hello"), st.button("Click"), st.image("pic.png")
# 📊 Display data: st.dataframe(df), st.plotly_chart(fig), st.write("Text")
# 🚀 Create UI: st.slider("Range", 0, 100), st.selectbox("Choose", options), st.file_uploader("Upload")

asyncio
# 🔄 Run async tasks: await asyncio.sleep(1), asyncio.run(main()), asyncio.gather(*tasks)
# 🌐 Handle coroutines: async def fetch(), await coro(), asyncio.create_task(func())
# ⏳ Manage event loops: loop = asyncio.get_event_loop(), loop.run_until_complete(), asyncio.ensure_future()

websockets
# 🌐 WebSocket server: async with websockets.serve(handler, "localhost", 8765): await asyncio.Future()
# 📡 Client connect: async with websockets.connect("ws://localhost:8765") as ws: await ws.send("Hi")
# 🔊 Real-time comms: async for msg in ws: print(msg), await ws.recv(), ws.send("Response")

pillow
# 🖼️ Load images: img = Image.open("file.png"), img.resize((100, 100)), img.save("out.png")

# 📥 Save recording: with open("recording.wav", "wb") as f: f.write(audio_recorder())

nest_asyncio
# 🔧 Fix nested loops: nest_asyncio.apply(), asyncio.run(main()), loop.run_until_complete(coro())
# 🌐 Enable async in sync: nest_asyncio.apply() before asyncio.run() in Jupyter/Streamlit
# ⏳ Patch event loop: import nest_asyncio; nest_asyncio.apply() for multiple event loops

streamlit-paste-button
# 📋 Paste images: result = paste_image_button("Paste"), if result.image_data: st.image(result.image_data)
