How can I use cachetools in Python?
You can use the cachetools library to implement caching in Python. It provides various cache types like LRU, TTL, and more.
What is the difference between LRU and TTL caches?
LRU (Least Recently Used) evicts the least recently accessed items, while TTL (Time To Live) evicts items after a specified time.
Can you show me a simple example of using an LRU cache?
Sure! Here's a basic example:
from cachetools import LRUCache
cache = LRUCache(maxsize=3)
cache['a'] = 1
cache['b'] = 2
cache['c'] = 3
print(cache)
cache['d'] = 4 # This will evict 'a'
print(cache)
