Yes, this is the problem with these tiny examples, we don't know at which
point we must simplify them...

Thanks to everyone for answers..
*but*, if you want to add more logic in the setters, you could want to add two
extra methods :
def _setsquare(self, v) :
# some extra logic here
self._square = s
def fsetsquare(self,s):
self

Hello everyone,
I try to set two properties, "value" and "square" in the following code,
and arrange it in such way that setting one property also sets another
one and vice versa. But the code seems to get Python into infinite loop:

^^
or just:
self._value = val
