📝 Python To-Do List CLI

A lightweight command-line task manager that saves your tasks to a local text file. No database, no setup — just Python.

---

✨ About

A minimal, no-frills to-do list manager built in pure Python. Tasks persist across sessions via a simple text file (todo.txt). Built as a beginner-friendly utility to practice file I/O, list manipulation, and CLI design — no external libraries needed.

🎯 Features

• ➕ Add tasks
• 📋 View all tasks with numbered listing
• ❌ Remove tasks by number
• 💾 Auto-save — tasks persist in todo.txt between runs
• 🪶 Zero dependencies — uses only Python's standard library

🛠️ Tech Stack

• Python 3.6+ — uses f-strings
• os module — checks if the file exists

🧠 What I Learned

• File I/O — reading and writing text files in Python
• List manipulation — append, pop, enumerate
• Error handling — using try/except to catch invalid input
• Persistent storage — saving state between program runs without a database
• Function decomposition — splitting code into small, single-purpose functions
