Documentation

This Python code defines three functions:

• greet(name): This function takes a string name as input and returns a greeting string "Hello, name!".
• add_numbers(a, b): This function takes two integers a and b as input and returns their sum.
• main(): This function is the main function of the program. It prompts the user for their name, greets them using the greet() function, then prompts for two numbers and calculates their sum using the add_numbers() function.

The code also includes docstrings for each function, which provide a concise description of what the function does, its arguments, and its return value.

Usage

To use this code, simply run the Python script. The script will first prompt you for your name, then greet you. It will then prompt you for two numbers and display their sum.

Example

Enter your name: John Hello, John! Enter the first number: 5 Enter the second number: 10 The sum of 5 and 10 is 15
