What
Python 3.8 adds great descriptor to functools: cached_property. Technically all required APIs was available since python 3.6, but it is what it is.
This package is a backport of this functionality for python 3.6 and 3.7.
How to use
from backports.cached_property import cached_propertyAnd then python 3.8 documentation will work (because code is minimally changed):
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 property, with the addition of caching. Useful for expensive computed properties of instances that are otherwise effectively immutable.
Example:
class DataSet:
def __init__(self, sequence_of_numbers):
self._data = sequence_of_numbers
@cached_property
def stdev(self):
return statistics.stdev(self._data)
@cached_property
def variance(self):
return statistics.variance(self._data)
