Create properties that are only computed the first time they are called.

Project Description

Only compute the value of properties the first time they are called. The easiest way to explain it is by example.

Bad:

class Foo(object):
    def __init__(self):
        self._bar_cache = None

    @property
    def bar(self):
        if self._bar_cache is None:
            self._bar_cache = 2 * 2 * 2
        return self._bar_cache

Good:

from memoize import mproperty

class Foo(object):
    @mproperty
    def bar(self):
        return 2 * 2 * 2
