Hello!
I have got a Python "Device" Object which has got a attribute (list)
called children which my contain several other "Device" objects. I
implemented it this way in order to achieve a kind of parent/child
relationship.
Now I would like to get all children of a given "Device" object and
thought that it would be the best way to use recursive function.
This is what I got so far:
def getAllChildren(self, children=[]):
if self.children:
children.extend(self.children)
for child in self.children:
child.getAllChildren(children)
return children
Unfortunately, it doesn't work like expected since the default parameter
children=[] is evaluated only once. That's why the children list becomes
larger and larger after calling the method several times but I can't
think of another possibility.
Do you have any ideas?
