Password Manager Using Python

A lightweight, terminal-based password manager built with Python.
Store, retrieve, update and delete your website credentials — all from the command line.

---

Overview

Password Manager is a beginner-friendly Python CLI project that demonstrates core programming concepts — file I/O, dictionaries, loops and functions — while solving a real-world problem: managing passwords across multiple websites without a browser.

All credentials are persisted locally in a passwords.txt file and loaded into memory at runtime, enabling fast lookups and edits throughout the session.

How It Works

1. On startup — passwords.txt is read and parsed into a Python dictionary (passwords{}) for fast in-memory access.
2. Save (Create) — New entries are appended to the file and added to the dictionary.
3. View / Search (Read) — Data is read directly from the in-memory dictionary.
4. Update / Delete (Write) — The dictionary is modified and the entire file is rewritten to stay in sync.
