Task: Write a function that takes in a list of numbers and outputs the mean of the numbers using the formula for mean. Do this without any built-in functions like sum(), len(), and, of course, mean()
In [37]:
def mean_function(num_list):
number_of_elements = 0
sum_of_numbers = 0
for number in num_list:
number_of_elements = number_of_elements + 1
sum_of_numbers = sum_of_numbers + number
mean_of_numbers = sum_of_numbers/number_of_elements
return mean_of_numbers
