2to3

Automated Python 2 to 3 code conversion. More information: https://docs.python.org/3/library/2to3.html.

• Display the changes that would be performed without performing them (dry-run):
  2to3 {{path/to/file.py}}
• Convert a Python 2 file to Python 3:
  2to3 --write {{path/to/file.py}}
• Convert specific Python 2 language features to Python 3:
  2to3 --write {{path/to/file.py}} --fix={{raw_input}} --fix={{print}}
• Convert all Python 2 language features except the specified ones to Python 3:
  2to3 --write {{path/to/file.py}} --nofix={{has_key}} --nofix={{isinstance}}
• Display a list of all available language features that can be converted from Python 2 to Python 3:
  2to3 --list-fixes
• Convert all Python 2 files in a directory to Python 3:
  2to3 --output-dir={{path/to/python3_directory}} --write-unchanged-files --nobackups {{path/to/python2_directory}}
• Run 2to3 with multiple threads:
  2to3 --processes={{4}} --output-dir={{path/to/python3_directory}} --write --nobackups --no-diff {{path/to/python2_directory}}
