**Source code:** :source:`Lib/functools.py`
The :mod:`functools` module is for higher-order functions: functions that act on or return other functions. In general, any callable object can be treated as a function for the purposes of this module.
The :mod:`functools` module defines the following functions:
Simple lightweight unbounded function cache. Sometimes called `"memoize" <https://en.wikipedia.org/wiki/Memoization>`_.
Returns the same as ``lru_cache(maxsize=None)``, creating a thin wrapper around a dictionary lookup for the function arguments. Because it never needs to evict old values, this is smaller and faster than :func:`lru_cache()` with a size limit.
For example::
The cache is threadsafe so that the wrapped function can be used in multiple threads. This means that the underlying data structure will remain coherent during concurrent updates.
It is possible for the wrapped function to be called more than once if another thread makes an additional call before the initial call has been completed and cached.
Transform a method of a class into a property whose value is computed once and then cached as a normal attribute for the life of the instance. Similar to :func:`property`, with the addition of caching. Useful for expensive computed properties of instances that are otherwise effectively immutable.
Example::
The mechanics of :func:`cached_property` are somewhat different from :func:`property`. A regular property blocks attribute writes unless a setter is defined. In contrast, a *cached_property* allows writes.
