Reset the cache in lru_cache

Question

Is there any way of over-riding the lru_cache in python?

Specifically if I have a function such as:

  import functools

  @functools.lru_cache(maxsize=None)
  def function_of_interest(variables):

       ...
       return(processed_values)

Is is possible to reset the cache, and hence run-run the function?

If my understanding is correct, you can just use cache_clear on the decorated function. If you've filled the cache by running it, this clears all indicators for you, that is:

function_of_interest.cache_clear()

Should result in a cache_info of:

CacheInfo(hits=0, misses=0, maxsize=None, currsize=0)

Do you know how to access it when the cache is on a property? – Natim Jun 08 '21 at 09:36
