What are some examples of using cachetools in Python?

Cachetools is a Python library that provides various caching strategies. For example, you can use a simple LRU (Least Recently Used) cache to store results of expensive function calls.

Can you show me a code snippet for an LRU cache?

Sure! Here's a simple example:

from cachetools import LRUCache

cache = LRUCache(maxsize=100)

def expensive_function(x):
    if x in cache:
        return cache[x]
    result = x * x  # Simulating an expensive operation
    cache[x] = result
    return result

How do I install cachetools?

You can install cachetools using pip. Just run pip install cachetools in your terminal.

Are there other caching strategies available in cachetools?

Yes, cachetools offers several strategies like TTLCache (Time-To-Live), LFUCache (Least Frequently Used), and more.
