# YOUR PROGRAM SHOULD WORK LIKE THIS:
# <code>
# >>> test_function({{my_function}}, ((76, 24, 11, 93, 28, 27, 95, 4, 39, 40, 11, 92),))
# Tester reports function returned value 264, type int.
# Tester reports test completed successfully.
# </code>
#
# <code>
# >>> test_function({{my_function}}, ((19, 88, 43, 15, 95, 89, 68, 72, 9),))
# Tester reports function returned value 228, type int.
# Tester reports test completed successfully.
# </code>
#
# <code>
# >>> test_interactive_task((0,35,3))
# Enter the start value of the range: 0
# Enter the stop value of the range: 35
# Enter the step value of the range: 3
# The sum of all even numbers from 0 to 35 by 3 is 90.
# Tester reports test completed successfully.
# </code>

# Write a function that
#   takes in a list of numbers,
#   calculates the sum of all the EVEN numbers in the list
#   and returns the sum
#
# (see the "SHOULD WORK LIKE THIS" section for exact input and output format)
