A diff against the original source file is printed. 2to3 can also write the needed modifications right back to the source file. (A backup of the original file is made unless :option:`-n` is also given.) Writing the changes back is enabled with the :option:`-w` flag::
11
$ 2to3 -w example.py
$ 2to3 -w example.py

After transformation, :file:`example.py` looks like this::
Après transformation,: file:`exemple.py` ressemble à ceci::
