Packages

The easiest way to obtain Python enabled clingo packages is using Anaconda. Packages are available in the Potassco channel. First install either Anaconda or Miniconda and then run: conda install -c potassco clingo.
Packages for clingo are available in the Linux distributions Debian, Ubuntu, and Arch Linux. (For historic reasons, the clingo package is split into gringo and clasp on Ubuntu/Debian.)
For Mac OS X, clingo packages are available in homebrew and macports.
