U-nderstand

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

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

  • A: The function should accept a list of strings tasks and print each task on a new line with a numbered format, preceded by the header "Pooh's To Dos:".

• Q: How should the tasks be numbered?

  • A: The tasks should be numbered starting from 1 and each task should appear on a new line in the format 1. Task 1, 2. Task 2, etc.

• Q: What happens if the list of tasks is empty?

  • A: The function should only print the header "Pooh's To Dos:" and nothing else.

• The function print_todo_list() should take a list of strings tasks and print each task on a new line, prefixed with its position in the list.

HAPPY CASE
Input: ["Count all the bees in the hive", "Chase all the clouds from the sky", "Think", "Stoutness Exercises"]
Expected Output: 
Pooh's To Dos:
1. Count all the bees in the hive
2. Chase all the clouds from the sky
3. Think
4. Stoutness Exercises


EDGE CASE
Input: []
Expected Output:
Pooh's To Dos:

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Define a function that prints each task with its corresponding number in the list.

1. Define the function `print_todo_list(tasks)`.
2. Print the header "Pooh's To Dos:".
3. Iterate over the range of indices from 1 to len(tasks).
4. Print each task in the format "i. task" where `i` is the current index.

⚠️ Common Mistakes

• Forgetting to adjust the index when printing tasks.

I-mplement

Implement the code to solve the algorithm.

def print_todo_list(tasks):
    # Print the header
    print("Pooh's To Dos:")
    
    # Iterate over the range of indices from 1 to len(tasks)
    for i in range(1, len(tasks) + 1):
        # Print each task in the specified format
        print(f"{i}. {tasks[i - 1]}")
