A copy & paste backport of Python 3.3's shutil.which function.

Usage

First, install the package: pip install shutilwhich

Importing the package:

import shutilwhich

will monkey-patch the shutil package, so from that point on you can simply import the which function:

from shutil import which

To keep things a little more concise, you can also import which directly from shutilwhich:

from shutilwhich import which

This will still monkeypatch the shutil module. On Python 3.3 and above, the module never do anything but return the stdlib shutil.which function.
