| If a class has an argument with a default of an empty dictionary,
| then all instances of the same class will point to the same
| dictionary, unless the dictionary is explictly defined by the
| constructor.
This is part of the language semantics, and so not a bug. The default
values of optional arguments are evaluated when the function/method is
compiled. You may consider the semantics ill-advised, but it is
intentional.
| class foo:
|
| def __init__(self,attribs={}):
| self.attribs=attribs;
| return None;
I usually write this as:
class Foo:
def __init__(self, attribs = None):
self.attribs = attribs or {}
