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

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 follow these best practices: 1. Use the '2to3' tool to automate code translation. 2. Test your code thoroughly after migration. 3. Use libraries that support both versions during the transition. 4. Gradually phase out Python 2 dependencies.

What tools can help with the migration process?

Some useful tools include '2to3' for code conversion, 'futurize' for compatibility, and 'six' for writing code that works on both versions.

How can I ensure my code is compatible with both versions?

To ensure compatibility, you can use the 'six' library, which provides utility functions for writing code that runs on both Python 2 and 3. Additionally, write tests to verify functionality in both environments.

What common issues should I look out for during migration?

Common issues include differences in string handling, integer division, and changes in standard library modules. Pay special attention to print statements and exception handling.
