How can I use the cachetools library in Python?

The cachetools library provides various caching strategies for Python. You can use it to store results of expensive function calls.

Can you give me an example of how to implement a simple cache?

Sure! Here's a basic example using LRUCache:

from cachetools import LRUCache

cache = LRUCache(maxsize=100)

def get_data(key):
    if key in cache:
        return cache[key]
    else:
        # Simulate a data fetch
        data = fetch_data_from_source(key)
        cache[key] = data
        return data

What is the difference between LRUCache and TTLCache?

LRUCache evicts the least recently used items, while TTLCache evicts items after a specified time-to-live (TTL).
