Hi Marco (and everybody), in another thread you showed your code and made extensive use of property(). Wrongful use I might say. Let's see an example: >>> class C(object): ... def __init__(self): self._x = None ... def getx(self): return self._x - 10 ... def setx(self, value): self._x = -value ... def delx(self): del self._x ... x = property(getx, setx, delx, "I'm the 'x' property.") ... >>> c = C() >>> c.x = 23 >>> c.x -33
as you can see you don't call setx() or getx() directly, you just operate straight with x and setx() or getx() get automatically called (c.x is given -value, that is -23 on setx(), and then we subtract 10 to -23 giving -33). What's more, you don't use property() nor setters and getters to do """ self._x = value """ that makes no sense, in that case you would use just x and get done with it. You usually use c.x = 22 and if you have the need of a setter or getter to process x before setting or getting *then* you start using the setters and getters. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
