Définition

class property(builtins.object):

help(property)

Property attribute.

  fget
    function to be used for getting an attribute value
  fset
    function to be used for setting an attribute value
  fdel
    function to be used for del'ing an attribute
  doc
    docstring

Typical use is to define a managed attribute x:

class C(object):
    def getx(self): return self._x
    def setx(self, value): self._x = value
    def delx(self): del self._x
    x = property(getx, setx, delx, "I'm the 'x' property.")

Decorators make defining new properties or modifying existing ones easy:

class C(object):
    @property
    def x(self):
        "I am the 'x' property."
        return self._x
    @x.setter
    def x(self, value):
        self._x = value
    @x.deleter
    def x(self):
        del self._x
