Python To-Do CLI

A simple command-line to-do list application written in Python. Tasks are stored in a local JSON file, so your list is saved between runs.

Features

• Add a new task
• List all tasks (with completion status)
• Mark a task as completed
• Remove a task

Data storage

Tasks are saved in todos.json, which is created automatically the first time you add a task. This file is excluded from version control (see .gitignore), so each user starts with their own empty list.

To see what the data structure looks like, check todos-example.json.

Project structure

todo-cli/
├── main.py              # Entry point, menu loop
├── todos.py              # Core logic: load, save, add, list, complete, remove
├── todos-example.json    # Sample data structure
├── .gitignore
└── README.md

What I learned

• Reading from and writing to files in Python
• Working with JSON data
• Structuring a small project across multiple files
• Basic error handling (missing file, invalid input, empty list)
