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