If you download and install gmpy, it's easy: >>> import gmpy >>> gmpy.comb(9,2) mpz(36) However, there's no equivalent function built into Python, if that's what you're asking (gmpy's a third-party extension). It's of course easy to write one for yourself, if you want the functionality but don't want to download gmpy and don't care for gmpy's superb speed.
