Average of all values in a list - is there a more 'Pythonic' way to do this?

So I'm following a beginner's guide to Python and I got this exercise: Create a list containing 100 random integers between 0 and 1000 (use iteration, append, and the random module). Write a function called `average` that will take the list as a parameter and return the average. I solved it easily in a few minutes but the chapter also mentions several ways to traverse through lists and assign multiple values to lists and variables that I'm not sure if I fully understand yet, so I don't know if it's possible to do this in less lines. This is my answer: ``` import random def createRandList(): newlist = [] for i in range(100): newint = random.randrange(0,1001) newlist.append(newint) return newlist def average(aList): totalitems = 0 totalvalue = 0 for item in aList: intitem = int(item) totalitems = totalitems + 1 totalvalue = totalvalue + intitem averagevalue = totalvalue/totalitems return averagevalue myList = createRandList() listAverage = average(myList) print(myList) print(listAverage) ``` Thanks in advance!
