Write a python function that takes a list from the user and then calculates the average of the list.

def ave3():

    list2 = []

    sum2=0

    z = int(input("size of the list"))

    for i in range (z):

        inn = int(input("enter the element"))

        list2.append(inn)

    for i in range (z):

        sum2=sum2+list2[i]

    a = sum2 / z

    print("average of the list = {}".format(a))

ave3()
