@ -102,18 +102,10 @@ The :mod:`functools` module defines the following functions:
``__slots__`` without including ``__dict__`` as one of the defined slots
(as such classes don't provide a ``__dict__`` attribute at all).
If a mutable mapping is not available or if space-efficient key sharing
is desired, an effect similar to :func:`cached_property` can be achieved
by a stacking :func:`property` on top of :func:`cache`::
class DataSet:
def __init__(self, sequence_of_numbers):
self._data = sequence_of_numbers
@property
@cache
def stdev(self):
return statistics.stdev(self._data)
If a mutable mapping is not available or if space-efficient key sharing is
desired, an effect similar to :func:`cached_property` can also be achieved by
stacking :func:`property` on top of :func:`lru_cache`. See
:ref:`faq-cache-method-calls` for more details on how this differs from :func:`cached_property`.
