How do I clear cache in Python?

You can clear cache in Python by using the cache_clear() method on cache objects or by deleting cache files.

Can you show me an example of using cache_clear()?

Sure! If you're using functools.lru_cache, you can clear the cache like this:

from functools import lru_cache

@lru_cache(maxsize=32)
def expensive_function(x):
    # Some expensive computation
    return x * x

# Clear the cache
expensive_function.cache_clear()

What if I'm using a different caching library?

If you're using a different library, the method to clear the cache may vary. For example, with diskcache, you can use cache.clear().

Are there any performance implications of clearing the cache frequently?

Yes, clearing the cache frequently can lead to performance degradation since cached results will need to be recomputed.
