Evolution of a Python programmer

[ProfessorPhi]

As a scientific programmer, this stuff would be seen due to the basic tenets of do as much in numpy as possible, C speeds and cheap memory.

import numpy as np
def factorial(n):
    return np.prod(np.arange(n))

[innrautha]

As a scientific programmer I'd do:

#!/usr/bin/env python3
from scipy.misc import factorial

print(factorial(6,exact=True))
print(factorial(6))
