What are the best practices for migrating from Python 2 to Python 3?

When migrating from Python 2 to Python 3, it's essential to start by ensuring your code is compatible. Use tools like 2to3 or modernize to help with the transition.

Are there any specific libraries I should check for compatibility?

Yes, check libraries like NumPy, Pandas, and Django. Most popular libraries have already been updated for Python 3.

What about handling print statements?

In Python 3, print is a function, so you'll need to change print statements from print 'text' to print('text').

How can I test my code after migration?

You can use unit tests to verify functionality. Consider using pytest or unittest to ensure your code behaves as expected.

Any tips for dealing with string handling changes?

Yes, remember that strings are Unicode by default in Python 3. You may need to adjust how you handle byte strings and encodings.
