Geometric mean in Python

Here is a small snippet of code that can be used to compute geometric mean of a set of numbers in Python:


import math

def geomean(listofvalues):
    s=0
    for v in listofvalues:
        s+=math.log10(v)
    s=s/len(listofvalues)
    s=math.pow(10,s)
    return s

# main function
def main():
    #test sample
    list=[4,4,4,5]
    y=geomean(list)
    print(y)

# main fucntion call
if __name__ == "__main__":
    main()
