Understand what the interviewer is asking for by using test cases and questions about the problem.

• Q: What should the function print_catchphrase() do?

  • A: The function should accept a string character and print the corresponding catchphrase from a predefined set. If the character is not recognized, it should print a default message indicating that the catchphrase is unknown.

• Q: What characters are expected, and what are their catchphrases?

  • A: The expected characters and their catchphrases are:
    • "Pooh": "Oh bother!"
    • "Tigger": "TTFN: Ta-ta for now!"
    • "Eeyore": "Thanks for noticing me."
    • "Christopher Robin": "Silly old bear."

• Q: What should be done if the input character is not in the list?

  • A: The function should print "Sorry! I don't know <character>'s catchphrase!".

• The function print_catchphrase() should take a single parameter, character, and print the corresponding catchphrase based on the given character. If the character does not match any in the table, it should print a default message.

HAPPY CASE
Input: "Pooh"
Expected Output: Oh bother!

Input: "Tigger"
Expected Output: TTFN: Ta-ta for now!

EDGE CASE
Input: "Piglet"
Expected Output: Sorry! I don't know Piglet's catchphrase!

Input: " (empty string)
Expected Output: Sorry! I don't know 's catchphrase!

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Define a function that uses conditionals to match the input character to a predefined set of catchphrases, printing the appropriate message.

1. Define the function `print_catchphrase(character)`.
2. Use conditional statements to check the value of `character`.
3. Print the corresponding catchphrase if the character matches one from the table.
4. If the character does not match any in the table, print a default message.

⚠️ Common Mistakes

• Incorrectly formatting the strings (ensure they match exactly).
• Forgetting to handle characters not listed in the table.

Implement the code to solve the algorithm.

def print_catchphrase(character):
    if character == "Pooh":
        print("Oh bother!")
    elif character == "Tigger":
        print("TTFN: Ta-ta for now!")
    elif character == "Eeyore":
        print("Thanks for noticing me.")
    elif character == "Christopher Robin":
        print("Silly old bear.")
    else:
        print(f"Sorry! I don't know {character}'s catchphrase!")
