TypeError of the metaclass in python

Question

I wrote the follow program but it didn't work.What wrong with it?

def h(self):
    print "Hello World"
if __name__ == '__main__':
    hello = type('HelloThread', bases=(threading.Thread,object), dict=dict(hello=h))

The error when it run is that:

TypeError: type.__init__() takes no keyword arguments

My python version is the python2.7

What are you trying to achieve? What is the expected output? — AKS

The error specifically says type.__init__() takes no keyword arguments so don't use keyword arguments when initiating type:

hello = type('HelloThread', (threading.Thread, object), dict(hello=h))
