How can I implement cachetools in Python?

You can implement cachetools by installing the library using pip and then using its caching decorators or classes.

What are the different types of caches available in cachetools?

Cachetools provides several types of caches, including LRUCache, TTLCache, and RRCache, each serving different use cases.

Can you show me a simple example of using LRUCache?

Sure! Here's a simple example:

from cachetools import LRUCache

cache = LRUCache(maxsize=3)

cache['a'] = 1
cache['b'] = 2
cache['c'] = 3

print(cache)

This will create an LRU cache with a maximum size of 3.

How do I handle cache expiration with TTLCache?

You can use TTLCache by specifying a time-to-live (TTL) for each entry. For example:

from cachetools import TTLCache

cache = TTLCache(maxsize=100, ttl=300)  # 300 seconds TTL
