1st Script written doesn't output anything. Need some else's eyes

In your "main" function, you need to change you're elif's to look like the "if" statement, you can also remove all the redundant parenthesis:

        if operation == '+':
            print(add(var1, var2))
        elif operation == '-':
            print(sub(var1, var2))
        elif operation == '*':
            print(mul(var1, var2))
        else:
            print(div(var1, var2))

Then you need to call the function "main()". Add this to the end of your script:

if __name__ == "__main__":
    main()
