To-Do List Application

Overview

This is a simple command-line To-Do List application implemented in Python. It allows users to manage their tasks efficiently by providing functionalities to add tasks, list tasks, update tasks, delete tasks, save tasks to a file, and load tasks from a file.

Prerequisites

Python 3.x
pickle (for serialization, already included in Python standard library)

Usage

Run the program:
- Open a terminal or command prompt.
- Navigate to the directory where the todo_list_app.py file is located.
- Run the program by typing python todo_list_app.py and pressing Enter.
Interact with the program:
- Once the program is running, you'll see a menu with options to perform various tasks.
- Follow the prompts to add tasks, list tasks, update tasks, delete tasks, save tasks to a file, or load tasks from a file.
- To exit the program, select the option to exit from the menu.

Functionalities

Add Task: Add a new task to the to-do list with a title and description.
List Tasks: View all tasks in the to-do list along with their statuses (completed or pending).
Update Task: Modify an existing task's title, description, or completion status.
Delete Task: Remove a task from the to-do list.
Save to File: Save the current state of the to-do list to a file for future use.
Load from File: Load tasks from a file and restore the to-do list to a previous state.

Implementation Details

The application consists of two classes: Task and ToDoList.
Task class represents an individual task with attributes such as title, description, and completion status.
ToDoList class manages the list of tasks and provides methods to perform various operations on tasks.
Tasks are stored in a list within the ToDoList class.
Task data is serialized and deserialized using the pickle module for saving and loading from files.
