SimpleXMLRPCServer help

[Eric Texier]

help(SimpleXMLRPCServer) describe how to install an instance
on the server:

2. Install an instance:

    class MyFuncs:
        def __init__(self):
            # make all of the string functions available through
            # string.func_name
            import string
            self.string = string
        def pow(self, x, y): return pow(x, y)
        def add(self, x, y) : return x + y
    server = SimpleXMLRPCServer(("localhost", 8000))
    server.register_instance(MyFuncs())
    server.serve_forever()

BUT I cannot figure out the syntax to access it from a client point of
view
I will appreciate a quick example even not tested.
Thanks,
Eric
