nixpkgs/pkgs/development/interpreters/python/3.1/default.nix
Peter Simons bba637c718 pkgs/development/interpreters/python/3.1: renamed this package to "python3"
Python version 3.x is really quite different from 2.x. Using a new name
for the package prevents Nix from performing unintended updates to the
3.x version.
