  • To avoid doing "some time-consuming calculations" that have already been done – Sayse May 27 '22 at 11:18
  • You need to store the result somewhere - you could have used a LRU cache ... or you declare something before the function so the funciton can use it. https://docs.python.org/3/library/functools.html#functools.lru_cache - a lru_chace caches "the inputs of a function and what it returns" - if the same inputs come along it will return the last return again without recomputing. – Patrick Artner May 27 '22 at 11:19
