3 2to3 - Automated Python 2 to 3 code translation
8 2to3 is a Python program that reads Python 2.x source code and applies a series
10 contains a rich set of fixers that will handle almost all code.  2to3 supporting

19 Using 2to3
22 2to3 will usually be installed with the Python interpreter as a script.  It is
25 2to3's basic arguments are a list of files or directories to transform.  The
36 It can be converted to Python 3.x code via 2to3 on the command line:
40    $ 2to3 example.py
42 A diff against the original source file is printed.  2to3 can also write the
49    $ 2to3 -w example.py
61 By default, 2to3 runs a set of :ref:`predefined fixers <2to3-fixers>`.  The
68    $ 2to3 -f imports -f has_key example.py
74    $ 2to3 -x apply example.py
82    $ 2to3 -f all -f idioms example.py
86 Sometimes 2to3 will find a place in your source code that needs to be changed,
87 but 2to3 cannot fix automatically.  In this case, 2to3 will print a warning
91 2to3 can also refactor doctests.  To enable this mode, use the :option:`!-d`
99 Since some print statements can be parsed as function calls or statements, 2to3
100 cannot always read files containing the print function.  When 2to3 detects the
115 The :option:`!-W` or :option:`!--write-unchanged-files` flag tells 2to3 to always
130    $ 2to3 -n -W --add-suffix=3 example.py
141    $ 2to3 --output-dir=python3-version/mycode -W -n python2-version/mycode
149 Each step of transforming code is encapsulated in a fixer.  The command ``2to3
150 -l`` lists them.  As :ref:`documented above <2to3-using>`, each can be turned on
