# 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}}`
