pythonpy

'python -c', with tab completion and shorthand

pythonpy is an utility that facilitates the usage of Python one-liners. The command 'py' evaluates a string consisting of any Python expression. It can do anything from simple arithmetic to complex operations, importing modules automatically. It also comes with tab completion. Its usage is not restricted to single expressions only. There's also the possibility to pipe data from stdin and to stdout, even generating strings to be evaluated by other programs.
