📘 Python Crash Course – Chapter 8: Functions – Exercise 8-13 Solution

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

📝 Exercise 8-13

Task:
Build a profile of yourself by calling build_profile(), using your first and last names and three other key-value pairs that describe you

✅ Solution Code:


def build_profile(first, last, **user_info):
    """Build a dictionary containing everything we know about a user."""
    profile = {}
    profile['first_name'] = first
    profile['last_name'] = last
    for key, value in user_info.items():
        profile[key] = value
    print(profile)  
# Build a profile of yourself
user_profile = build_profile('John', 'Doe', location='New York', age=30, occupation='Engineer')

🧠 Code Explanation:

  1. Define the function with flexible arguments:

    The function build_profile(first, last, **user_info) is defined with three parameters:

    • first: Represents the user's first name.
    • last: Represents the user's last name.
    • **user_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 profile is created to store the user's information. The first and last names are added to the dictionary with keys 'first_name' and 'last_name'.

  3. Process additional key-value pairs:

    A for loop iterates through the user_info dictionary. Each key-value pair is added to the profile dictionary, allowing the function to dynamically include additional information about the user.

  4. Call the function to build a profile:

    The function is called with the user's first and last names, along with additional keyword arguments:

    • build_profile('John', 'Doe', location='New York', age=30, occupation='Engineer'): Builds a profile for a user named John Doe, including their location, age, and occupation.
  5. Display the profile:

    The resulting dictionary, which contains all the user's information, is displayed to confirm that the profile has been built correctly.

🔍 Output:


{'first_name': 'John', 'last_name': 'Doe', 'location': 'New York', 'age': 30, 'occupation': 'Engineer'}
