Simple mem cache client for python

simplememcache

simplememcache is a lightweight Python package providing a simple and efficient Least Recently Used (LRU) cache implementation. It allows you to cache and manage key-value pairs with a maximum size, automatically evicting the least recently used items when the cache reaches its limit.

Installation

You can install simplememcache using pip:

pip install simplememcache

Importing the package

from simplememcache.lru import LRUCache

Creating a cache instance

# Create an LRU cache with a maximum size of 100 items
cache = LRUCache(max_size=100)

Inserting items into the cache

cache.insert("key1", "value1")
cache.insert("key2", 42)

Getting items from the cache

value = cache.get("key1")
print(value)  # Output: "value1"

Getting items with default value

value = cache.get_or_default("nonexistent_key", default="default_value")
print(value)  # Output: "default_value"

Upserting items into the cache

# Upsert (update or insert) an item into the cache
result = cache.upsert("key1", "new_value")
print(result)  # Output: False (key1 already existed, value updated)

Deleting items from the cache

deleted_value = cache.delete("key2")
print(deleted_value)  # Output: 42

Deleting items with default value

deleted_value = cache.delete_or_default("nonexistent_key", default="default_value")
print(deleted_value)  # Output: "default_value"

Checking the size of the cache

cache_size = cache.size
print(cache_size)  # Output: 1
