#returns the average of num1, num2, and num3
def average_3_numbers(num1, num2, num3):
    the_sum = num1+num2+num3
    average= the_sum/3
    return average

### Let's test our function:
#print( average_3_nums(3,4,5) )

#Returns the average of all the numbers in some_list
#some_list must be a list of numbers
def average_of_list(some_list):
    the_sum = sum(some_lst)
    length_of_list = len(some_list)
    average = the_sum / length_of_list
    return average

#lst = [3,4,5,6]
#print(average_of_list(lst))

### Note: You don't have to pre-create a list.
#You can place a new list directly in the function as the argument:
#print(average_of_list([2,3,4]))

### What happens if we pass the function an emtpy list?
#print(average_of_list([]))
