How do I troubleshoot issues during my Python migration?

I'm having trouble migrating my Python 2 code to Python 3. What should I do?

First, ensure you have a backup of your code. Then, use tools like 2to3 or modernize to help with the conversion.

I've run 2to3, but I'm still getting syntax errors. What could be wrong?

Check for print statements and exception handling, as they have changed in Python 3. Also, look for any library dependencies that may not be compatible.

How can I test my code after migration?

You can use unit tests to verify functionality. Consider using pytest or unittest to run your tests and catch any issues.

Are there any common pitfalls I should be aware of?

Yes, be cautious with string handling, integer division, and library changes. Review the official Python 3 migration guide for more details.
