A simple python decorator for defining properties that only run their fget function once.
* Free software: BSD license
What?
-----
A Python property that only calls its ``fget`` function one time. How many times have you written
this code (or similar)?
::
def class C(object):
@property
def name(self):
if not hasattr(self, '_name'):
self._name = some_expensive_load()
return self._name
I've written it just enough times to be annoyed enough to capture this module. The result is this::
from memoized_property import memoized_property
def class C(object):
@memoized_property
def name(self):
# Boilerplate guard conditional avoided, but this is still only called once
return some_expensive_load()
Why?
----
I couldn't find a pre-existing version of this on PyPI. I found one other on GitHub,
https://github.com/ytyng/python-memoized-property, but it was not published to PyPI.
