pip - uninstall package with dependencies

Virtualenvs in python are cheap but from time to time you will install something with pip on your system and when time comes removing all this crap could be difficult. I found this bash snippet¹ that will uninstall package with all dependencies:

for dep in $(pip show python-neutronclient | grep Requires | sed 's/Requires: //g; s/,//g') ; do
  pip uninstall -y $dep ;
done
pip uninstall -y python-neutronclient

Depending how you installed it, you might need to use sudo.
