Welcome to another solution from Python Crash Course by Eric Matthes.

📝 Exercise 8-12

Task:
Write a function that accepts a list of items a person wants on a sandwich . The function should have one parameter that collects as many items as the function call provides, and it should print a summary of the sand wich that is being ordered .
Call the function three times, using a different num ber of arguments each time

✅ Solution Code:


def make_sandwich(*items):
    print("Making a sandwich with the following items:")
    for item in items:
        print(f"- {item}")
    print("Your sandwich is ready!\n")
    print("---------------------------------------")

# Call the function three times with different number of arguments
make_sandwich("lettuce", "tomato", "cheese")
make_sandwich("ham", "turkey")
make_sandwich("peppers", "onions", "mayo", "mustard")

🧠 Code Explanation:

  1. Define the function with variable arguments:

    The function make_sandwich(*items) is defined with a parameter *items. The asterisk (*) allows the function to accept an arbitrary number of arguments, which are stored as a tuple.

  2. Iterate through the items:

    Inside the function, a for loop iterates through the items tuple. Each item represents an ingredient for the sandwich, and the loop processes all the provided arguments.

  3. Display the sandwich summary:

    The function displays a summary of the sandwich being made, listing all the ingredients provided in the function call. A separator line is printed after each sandwich for clarity.

  4. Call the function with different arguments:

    The function is called three times with varying numbers of arguments:

    • make_sandwich("lettuce", "tomato", "cheese"): Creates a sandwich with three ingredients.
    • make_sandwich("ham", "turkey"): Creates a sandwich with two ingredients.
    • make_sandwich("peppers", "onions", "mayo", "mustard"): Creates a sandwich with four ingredients.

🔍 Output:


Making a sandwich with the following items:
- lettuce
- tomato
- cheese
Your sandwich is ready!

---------------------------------------
Making a sandwich with the following items:
- ham
- turkey
Your sandwich is ready!

---------------------------------------
