This simple calculator program does the following:
1. Defines functions for basic arithmetic operations: add, subtract, multiply, and divide.
2. Presents a menu for the user to choose an operation.
3. Takes two numbers as input from the user.
4. Performs the selected operation and displays the result.
5. Asks if the user wants to perform another calculation.
6. Continues until the user chooses to exit.
You can run this script, and it will allow you to perform basic calculations. Feel free to ask if you have any questions or if you'd like to add more features to the calculator!
