Modernize is a Python program that reads Python 2 source code and applies a series of fixers to transform it into source code that is valid on both Python 3 and Python 2.7.
This allows you to run your test suite on Python 2.7 and Python 3 so you can gradually port your code to being fully Python 3 compatible without slowing down development of your Python 2 project.
python -m modernize command works like
python -m fissix, see fissix.
Here's how you'd rewrite a
python -m modernize -w example.py
It does not guarantee, but it attempts to spit out a codebase compatible
with Python 2.6+ or Python 3. The code that it generates has a runtime
dependency on six, unless the
--no-six option is used. Version 1.9.0 or later of
recommended. Some of the fixers output code that is not compatible with
Python 2.5 or lower.
Once your project is ready to run in production on Python 3 it's recommended to drop Python 2.7 support using pyupgrade

Using this tool does not affect licensing of the modernized code.
This library is a very thin wrapper around fissix, a fork of lib2to3.
