Python factorial Beispiele

Beispiel #1

Datei: probs.py Projekt: arnaudmkonan/pdapt

def choose(n, k):
    """ n choose k
    # example, say want to know ways to form committee of 3 students from 20 total students
    >>> choose(20,3)
    1140.0
    """
    return factorial(n) / (factorial(k) * factorial(n - k))

Beispiel #2

Datei: probs.py Projekt: matthewmacleod/pdapt

def choose(n,k):
    """ n choose k
    # example, say want to know ways to form committee of 3 students from 20 total students
    >>> choose(20,3)
    1140.0
    """
    return factorial(n) / (factorial(k)*factorial(n-k))

Beispiel #3
