# for older versions of python
average_method_one = sum(list) / len(list) 
# for python 2 convert len to a float to get float division
average_method_two = sum(list) / float(len(list))

# round answers using round() or ceil()
print(average_method_one)
print(average_method_two)

# A function that finds an average of a list of numbers

numbers = [1,2,3,4,5,6,7,889,102390143]

def find_average(number_list):

    total = 0

    for number in number_list:
        total += number
    
    average = total / len(number_list)

    print("Your average is:", average)
