What libraries can help with migrating Python 2 to 3?

There are several libraries that can assist with migrating from Python 2 to 3. Some popular ones include '2to3', 'futurize', and 'modernize'. Would you like to know more about how to use any of these?

Yes, can you explain how to use '2to3'?

Sure! '2to3' is a built-in tool that comes with Python. You can run it from the command line by typing 2to3 your_script.py. It will analyze your code and suggest changes. You can also use the -w option to write the changes back to the file.

What about 'futurize'? How is it different?

'futurize' is part of the 'future' package and helps you write code that is compatible with both Python 2 and 3. It provides a more gradual migration path. You can install it via pip and run it similarly to '2to3'.

Are there any other tools I should consider?

Yes, 'modernize' is another great tool that focuses on making your code compatible with Python 3 while maintaining Python 2 compatibility. It’s similar to 'futurize' but has a different approach.
