Fonction lru_cache - module functools

Signature de la fonction lru_cache

def lru_cache(maxsize=128, typed=False) 

Description

help(functools.lru_cache)

Least-recently-used cache decorator.

If *maxsize* is set to None, the LRU features are disabled and the cache
can grow without bound.

If *typed* is True, arguments of different types will be cached separately.
For example, f(decimal.Decimal("3.0")) and f(3.0) will be treated as
distinct calls with distinct results. Some types such as str and int may
be cached separately even when typed is false.

Arguments to the cached function must be hashable.

View the cache statistics named tuple (hits, misses, maxsize, currsize)
with f.cache_info().  Clear the cache and statistics with f.cache_clear().
Access the underlying function with f.__wrapped__.
