New submission from Matthew Walker <matto...@gmail.com>:
When initializing a class with an empty dict() object as a default initializer,
if it is not overridden, multiple instances of the class will share the
dictionary. IE:
class test(object):
def __init__(self, obj=dict()):
self.obj = obj
a = test()
b = test()
Then id(a.obj) points to the same location as id(b.obj). The behaviour I would
expect would be that a.obj and b.obj would be unique instances.
