OverflowError: n too large ''' import math if not n >= 0 : raise ValueError ( 'n must be >= 0' ) if math. ValueError: n must be exact integer > factorial(30.0) 265252859812191058636308480000000 It must also not be ridiculously large: > factorial(1e100) Traceback (most recent call last). ValueError: n must be >= 0 Factorials of floats are OK, but the float must be an exact integer: > factorial(30.1) Traceback (most recent call last). For example, > factorial(5) 120 ''' def factorial ( n ): '''Return the factorial of n, an exact integer >= 0. The example module supplies one function, factorial().
