Yes, in SciPy.

Help on function comb in module scipy.misc.common:
comb(N, k, exact=0)
Combinations of N things taken k at a time.
If exact==0, then floating point precision is used, otherwise
exact long integer is computed.
Notes:
- Array arguments accepted only for exact=0 case.
- If k > N, N < 0, or k < 0, then a 0 is returned.
