Question

Create a Python file num_utils.py that includes:

• A function sum_of_nums that accepts 1 or more number parameters and returns their sum without displaying anything
• A function product_of_nums that accepts 1 or more number  parameters and returns their product without displaying anything
• A function average_of_nums  that accepts 1 or more number  parameters and returns their average without displaying anything

Create a Python file test_num_utils.py that:

• Imports num_utils
• Defines a function test_num_utils that demonstrates the use of the utilities in num_utils.py
• Executes test_num_utils

Given below is the code for the question. Ensure to indent as shown in image. Please do rate the answer if it helped. Thank you.

num_utils.py
----
def sum_of_nums(*nums):
   s = 0
   for n in nums:
       s = s + n
   return s

def product_of_nums(*nums):
   prod = 1
   for n in nums:
       prod = prod * n
   return prod
  

def average_of_nums(*nums):
   n = len(nums)
   return sum_of_nums(*nums) / n

--------------
test_num_utils.py
--------------
import num_utils as nu

def test_num_utils():
print('Testing with 1 argument 5')
print('sum = ', nu.sum_of_nums(5))
print('product = ', nu.product_of_nums(5))
print('average = ', nu.average_of_nums(5))

print('Testing with 3 argument 2, 4, 6')
print('sum = ', nu.sum_of_nums(2, 4, 6))
print('product = ', nu.product_of_nums(2, 4, 6))
print('average = ', nu.average_of_nums(2, 4, 6))

test_num_utils()
