📘 Python Crash Course – Chapter 8: Functions – Exercise 8-10 Solution

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

📝 Exercise 8-10

Task:
Start with a copy of your program from Exercise 8-9 . Write a function called make_great() that modifies the list of magicians by add ing the phrase the Great to each magician’s name .
Call show_magicians() to see that the list has actually been modified

✅ Solution Code:


# List of magician's names
magicians = ["David Copperfield", "Harry Houdini", "Penn & Teller", "Dynamo", "Criss Angel"]


def show_magicians(magicians_list):
    """Print the names of the magicians in the list."""
    for names in magicians_list:
        print(names)
def make_great(magicians_list):
    """Modify the list of magicians by adding 'the Great' to each name."""
    for i in range(len(magicians_list)):
        magicians_list[i] = f"{magicians_list[i]} the Great Magician"
    return magicians_list


make_great(magicians)
show_magicians(magicians)
print(f' magician list: {magicians}')

🧠 Code Explanation:

  1. Create a list of magicians:

    The variable magicians is assigned a list containing the names of famous magicians, such as ["David Copperfield", "Harry Houdini", "Penn & Teller", "Dynamo", "Criss Angel"].

  2. Define the show_magicians function:

    This function accepts a list of magician names as a parameter and iterates through the list using a for loop. Each name in the list is displayed to confirm the current state of the list.

  3. Define the make_great function:

    This function modifies the list of magician names by appending the phrase 'the Great Magician' to each name. Here's how it works:

    • A for loop iterates through the list using the range() function to access each index.
    • Each name in the list is updated by concatenating the original name with the phrase 'the Great Magician'.
    • The modified list is returned to confirm the changes.
  4. Modify and display the list:

    The make_great function is called with the magicians list as an argument, modifying the list in place. The show_magicians function is then called to display the updated list of magician names.

  5. Verify the modified list:

    The modified magicians list is displayed to confirm that the changes made by the make_great function are persistent.

🔍 Output:


David Copperfield the Great Magician
Harry Houdini the Great Magician
Penn & Teller the Great Magician
Dynamo the Great Magician
Criss Angel the Great Magician
magician list: ['David Copperfield the Great Magician', 'Harry Houdini the Great Magician', 'Penn & Teller the Great Magician', 'Dynamo the Great Magician', 
'Criss Angel the Great Magician']
