Question

Define a function below called average numbers. The function takes one argument: a list of numbers. Complete the function so that it returns the average of the list of numbers. An empty list should have an average of zero.

Answer 1

Answer:

def average_numbers(lst):

   if len(lst) == 0:

       return 0

   else:

       total = 0

       for number in lst:

           total += number

       return total / len(lst)

Explanation:

Create a function called average_numbers that takes one parameter, lst

If the lst is empty, return 0.

Otherwise, add the numbers in the lst to the total using a for loop. When the loop is done, calculate and return the average, divide sum by length of the lst to calculate the average
