Task: Create a calculator program, which receives inputs from the user and depending on the selected operation, it will calculate Addition, Subtraction, multiplication, or division. Your program must be well validated. You must use loops, try and except, If else, functions, modules, arrays, variables (see further requirements below)

Requirements:

Comments including a brief description of the program, Input List and Output List, and full pseudocode. Place the pseudocode for each module above the module's Python code.

It must have at least one output.

It must have user input, then it must validate the user input. This means the user is not allowed to just enter any value. You must check the value, and ask the user to enter it again, and repeat this loop until the user enters a valid value.

Your program should be organized into separate modules. Each module should be "cohesive" and should only do one thing.

Use parameters and arguments to pass values into your modules (don't use global variables as much as you can).

The Python code should run correctly, and the logic should match your pseudocode.
