Generate a Simple Calculator in Python

[carmmmm]

Prompt for Code Generation

Please generate a Python script for a simple calculator. The script should include the following features:

1. Addition: The calculator should be able to add two numbers.
2. Subtraction: The calculator should be able to subtract one number from another.
3. Multiplication: The calculator should be able to multiply two numbers.
4. Division: The calculator should be able to divide one number by another, handling division by zero gracefully.

The script should be saved as calculator.py and should include:

• A function for each operation (add, subtract, multiply, divide).
• A simple command-line interface (CLI) to input numbers and choose the operation.

Please make sure the code is well-commented and easy to understand.

---

The generated file should be named calculator.py.
