Write a program add_function2.py that includes an add() function. The add() function takes two parameters, adds them together, and returns the sum to the main program.
The main() program should have the user enter two numeric values, and then send in those values to the add() function. Save the returned result in a variable, and then print out the variable in the main program.
Sample interaction:
Enter a number: 3.7
Enter another number: 2.3
After calling a function, the sum has been calculated as 6.0
