Hi,
I seem to be having a problem with a list being share across multiple
instantiations of it and dont quite understand why this is happening.
Class attributes are shared by all instances.
My class looks like this,
class Widget(object):
_parent = None
_children = []
Move this line
def __init__(self, parent=None):
self.parent = parent
to here.
@property
def children(self):
return self._children
@property
def parent(self):
return self._parent
@parent.setter
def parent(self, obj):
if obj:
obj._children.append(self)
self._parent = obj
now if i make instances and attach children like so
a = Widget()
b = Widget(a)
c = Widget(a)
d = Widget(c)
Basically all the objects end up sharing the _children list from `a`
instead of forming something like a tree. Any advice would be greatly
appreciated.
Thanks,
Daniel
