Subpackage Descriptions
single cachetools ======================================================================== :alt: Latest PyPI version :alt: Documentation build status :alt: CI build status :alt: Test coverage :alt: License :alt: Code style: black This module provides various memoizing collections and decorators, including variants of the Python Standard Library's `@lru_cache`_ function decorator. .. code-block:: python from cachetools import cached, LRUCache, TTLCache # speed up calculating Fibonacci numbers with dynamic programming @cached(cache={}) def fib(n): return n if n < 2 else fib(n - 1) + fib(n - 2) # cache least recently used Python Enhancement Proposals @cached(cache=LRUCache(maxsize=32)) def get_pep(num): url = 'http://www.python.org/dev/peps/pep-%04d/' % num with urllib.request.urlopen(url) as s: return s.read() # cache weather data for no longer than ten minutes @cached(cache=TTLCache(maxsize=1024, ttl=600)) def get_weather(place): return owm.weather_at_place(place).get_weather() For the purpose of this module, a *cache* is a mutable_ mapping_ of a fixed maximum size. When the cache is full, i.e. by adding another item the cache would exceed its maximum size, the cache must choose which item(s) to discard based on a suitable `cache algorithm`_. This module provides multiple cache classes based on different cache algorithms, as well as decorators for easily memoizing function and method calls.
