Hey guys, I have a question that I am a list of numbers and I need to use functions to find the average. I think I pretty much have it, but I can not get it to print the average. Can you please tell me what is wrong.
nums = [30,34,40,36,36,28,29,32,34,44,36,35,28,33,29,40,36,24,26,30,30,32,34,32,28,36,24,32]
def average(nums):
return sum(nums) / len(nums)
Have you tried print average(nums)? The code you have so far is just defining the function. It isn't doing anything with it. You have to call the function with its parameters and then do something with its return value (i.e. use the print function).
Basically your problem is this: int / int = int. You instead probably want one of these:
int / float = floatfloat / int = floatTry this:
nums = [30,34,40,36,36,28,29,32,34,44,36,35,28,33,
29,40,36,24,26,30,30,32,34,32,28,36,24,32]
def average(n):
return sum(n) / float(len(n))
print average(nums)
from __future__ import division to have the / operator represent "true division" as opposed to "floor division"; more here: python.org/dev/peps/pep-0238
