Fast(er) standard deviation calculation (compared to the standard library) for Python [experimental]

import fast_stdev
print(fast_stdev.stdev([1, 2, 4])) # Sample standard deviation
print(fast_stdev.pstdev([1, 2, 4])) # Population standard deviation

Run test.py to compare results and run times with the statistics.[p]stdev functions and NumPy's array.std.
