How do I migrate my project from Python 2 to Python 3?

Migrating from Python 2 to Python 3 involves several steps. First, you should ensure your code is compatible with Python 3. Have you checked your code for compatibility?

No, I haven't. What tools can I use to check compatibility?

You can use tools like 2to3, futurize, or modernize to help with the transition. Would you like guidance on how to use any of these tools?

Yes, please explain how to use 2to3.

2to3 is a Python program that reads Python 2 code and applies a series of fixers to transform it into valid Python 3 code. You can run it from the command line like this: 2to3 -w your_script.py. The -w flag will write the changes to the file.

What should I do after running 2to3?

After running 2to3, you should test your code thoroughly to ensure everything works as expected. It's also a good idea to review the changes made by 2to3 to understand the modifications.
