python: are property fields being cached automatically?

Question

My question is are the following two pieces of code run the same by the interpreter:

class A(object):
  def __init__(self):
     self.__x = None

  @property         


        

Answer 1

Python 3.2 onwards offers a built-in decorator that you can use to create a LRU cache:

@functools.lru_cache(maxsize=128, typed=False)

Alternatively, if you're using Flask / Werkzeug, there's the @cached_property decorator.

For Django, try from django.utils.functional import cached_property
