Write a function called is_even that takes one parameter and returns a boolean value. It should return True if the argument is even; it should return False otherwise. The is_even function should not print anything out or return a number. It should only take in a number and return a boolean.

Note: Be sure to include comments for all functions that you use or create.

For example, if you made a call like

is_even_number = is_even(4)
is_even_number should have the value True.

Once you’ve written this function, write a program that asks the user for integers and prints whether the number they entered is even or odd using your is_even function. You should let the user keep entering numbers until they enter the SENTINEL value.

Here is a sample run of the program:

Enter a number: 5
Odd
Enter a number 42
Even
Enter a number: -6
Even
Enter a number: 0
Done!
