Lesson 10.2: Mini Project 2 – To-Do List Manager

Introduction:
This project helps students create a To-Do List Manager using Python. It focuses on data storage, file handling, and CRUD operations (Create, Read, Update, Delete) to manage tasks efficiently.

1. Project Overview:

Features: Add task, view tasks, mark tasks as done, delete tasks
Stores tasks in a text file or JSON for persistence
Simple menu-driven interface

2. Step-by-Step Implementation:

Step 1 – Store Tasks:

Step 2 – Menu Interface:

def show_menu():

    print("\nTo-Do List Manager")

    print("1. View Tasks")

    print("2. Add Task")

    print("3. Delete Task")

    print("4. Exit")
load_tasks()

while True:

    show_menu()

    choice = input("Enter choice (1-4): ")

if choice == "1": print("\nTasks:") for idx, task in enumerate(tasks, 1): print(f"{idx}. {task}") elif choice == "2": task = input("Enter new task: ") tasks.append(task) save_tasks() elif choice == "3": task_no = int(input("Enter task number to delete: ")) if 0 < task_no <= len(tasks): tasks.pop(task_no - 1) save_tasks() else: print("Invalid task number") elif choice == "4": print("Exiting To-Do List Manager...") break else: print("Invalid choice")

3. Practical Tips:

Use functions to organize code
Validate task numbers before deletion
Extend project to mark tasks as completed or prioritize tasks
Consider using JSON to store more complex data

Learning Outcome of This Lesson:

Build a functional To-Do List Manager in Python
Implement file handling to save and load tasks
Apply CRUD operations for task management
Understand project structuring and user input validation
