class Vertex(tuple):
pass
class Positioned_Vertex(Vertex):
def __init__(self, a, b):
Vertex.__init__(a)
a=Positioned_Vertex((0,0,0), 1)
This gives:
TypeError: tuple() takes at most 1 argument (2 given)
It looks like the explicit call to Vertex.__init__ is never made and
Vertex.__init__ is implicitly called when a Positioned_Vertex is
created. Is there a way to work around this and call the constructor
with the intended argument list?
