Redis Server in Python

Overview

This project is a simple Redis-like in-memory key-value store implemented in Python. It supports essential Redis commands, including basic string operations, list operations, and database persistence.

Features

The server supports the following Redis commands:

• PING - Check if the server is alive.
• ECHO <message> - Echo back the provided message.
• GET <key> - Retrieve the value of a key.
• SET <key> <value> - Set a key to a specific value.
• EXISTS <key> - Check if a key is present.
• DEL <key1> [<key2> ...] - Delete one or more keys.
• INCR <key> - Increment the value of a key by one.
• DECR <key> - Decrement the value of a key by one.
• LPUSH <key> <value1> [<value2> ...] - Insert values at the head of a list.
• RPUSH <key> <value1> [<value2> ...] - Insert values at the tail of a list.
• SAVE - Save the database state to disk.
