python why doesnt this work

Question

from math import factorial
import math
def get_bernoulli(n):
    b = 0
    sum = 0
    for k in range (0, n-1):
        part = (factorial(n)) / factorial(k) * factorial(n+1 - k)))*b
        sum += part
        b = -(1/n+1)*sum

pycharm is complaining about n k and b. It displays unsolved reference. what does this means?

You never call `get_bernoulli` function. There's also no return statement, so what you are "getting"? — OneCricketeer, Dec 27 '16 at 16:20

No return statement is fine. The function will just return None. — , Dec 27 '16 at 21:41

Let's play count the parentheses in this line:

part = (factorial(n)) / factorial(k) * factorial(n+1 - k)))*b

4x - "("
6x - ")"
