Those who like clojure/lisp, can try with Hy [1]. The latest version removed Python 2 support, but previous versions would work on Python 2 and 3. Can directly run hy code, compile to pyc or readable python source files.

For functional programming aficionados that still prefer python, don't forget PyToolz [2] or single-source-file underscore.py [3].
