📘 Python Crash Course – Chapter 8: Functions – Exercise 8-14 Solution

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

📝 Exercise 8-14

Task:
Write a function that stores information about a car in a diction ary . The function should always receive a manufacturer and a model name .
It should then accept an arbitrary number of keyword arguments .
Call the func tion with the required information and two other name-value pairs, such as a color or an optional feature .
Your function should work for a call like this one:
car = make_car('subaru', 'outback', color='blue', tow_package=True)
Print the dictionary that’s returned to make sure all the information was stored correctly

✅ Solution Code:


ef make_car(manufacturer, model, **additional_info):
    car_info = {}
    car_info['manufactured by'] =manufacturer
    car_info['model no'] = model

    for name , value  in additional_info.items():
        car_info[name] = value  
    return car_info      
    
# Call the function with the required information and two other name-value pairs
car = make_car('subaru', 'outback', color='blue', tow_package=True)
print(car)

🧠 Code Explanation:

  1. Define the function with flexible arguments:

    The function make_car(manufacturer, model, **additional_info) is defined with three parameters:

    • manufacturer: Represents the car's manufacturer.
    • model: Represents the car's model name.
    • **additional_info: Allows the function to accept an arbitrary number of keyword arguments, which are stored as a dictionary.
  2. Create a dictionary:

    Inside the function, an empty dictionary named car_info is created to store the car's information. The manufacturer and model are added to the dictionary with keys 'manufactured by' and 'model no'.

  3. Process additional key-value pairs:

    A for loop iterates through the additional_info dictionary. Each key-value pair is added to the car_info dictionary, allowing the function to dynamically include additional details about the car.

  4. Call the function with car details:

    The function is called with the required manufacturer and model, along with additional keyword arguments:

    • make_car('subaru', 'outback', color='blue', tow_package=True): Creates a dictionary for a Subaru Outback with additional details such as color and tow package availability.
  5. Display the car information:

    The resulting dictionary, which contains all the car's details, is displayed to confirm that the information has been stored correctly.

🔍 Output:


{'manufactured by': 'subaru', 'model no': 'outback', 'color': 'blue', 'tow_package': True}
