Hey I am new to python so go easy, but I wanted to know how to make a program that calculates the maen.List = [15, 6, 6, 7, 8, 9, 40] def mean(): global themean, thesum for i in List: thecount = List.count(i) thesum = sum(List) themean = thesum / thecount Why doesn't this work?
You want to compute the arithmetic mean, I suppose .. Which is the sum of all, divided by the number of samples. i.e: If you have n numbers or elements, your mean (arithmetic) would be mean = sum(elements)/n. Right ?
And then, n also doesn't need to be in the loop and list.count(i) gives the occurrences of i in your list, which you don't need.
list.count(15) gives 1. thesum/list.count(15) doesn't change. -- ~Jugurtha Hadjar, -- https://mail.python.org/mailman/listinfo/python-list
