LifeStepsAI | Console Task Manager

A simple, menu-driven console application for managing tasks with in-memory storage. This application allows users to add, view, update, mark as complete, and delete tasks through an interactive menu interface.

Features

• Add Tasks: Create new tasks with titles and optional descriptions
• View Task List: Display all tasks with ID, title, and completion status
• Update Tasks: Modify existing task titles or descriptions
• Mark Complete: Toggle task completion status (Complete/Incomplete)
• Delete Tasks: Remove tasks from the system
• In-Memory Storage: All data is stored in memory (no persistent storage)
• Input Validation: Comprehensive validation for all user inputs

Requirements

• Python 3.11 or higher

Installation
