Multiplicate several numbers

[gruntfutuk]

Thanks for answer, but it didnt work :/
Do you have other suggestions? :)

Well, the code by nilamo:

import functools
import operator

def func(x):
    return 1 + (1/(x**2))

print(functools.reduce(operator.mul, map(func, range(1, 19))))

worked for me.

Output:
3.482783207792457
