Memoize

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
