What does it do?

Recursively converts every Python and IPython Notebook in a directory to Python 3.
The conversion is done with 2to3

How to use?

MAKE SURE YOU HAVE A BACKUP
The files will be overridden

convert_all directory
(not tested on Linux)

Will convert every .py and .ipynb files in directory to Python 3
directory can also be a single file

It should use all your CPU cores.

NOTES

• If you get UnicodeDecodeError when loading with pickle :
  Replace pickle.load with pickle.load(f,encoding='latin1')
  This is because Python 3 is using unicode.

The path finding supposes that on Linux, Python and 2to3 are in the PATH,
and that on Windows, Python is in the PATH.
If it is not the case, it will fail.

TODO

• test on Linux/Unix
