Can you provide a Python program to fix = prefix given the following:
I wrote the below code

    class SCGIAppHandler(SWAP, ):
        def __init__(self, *args, **kwargs):
            self.prefix = prefix
            self.app_obj = application
            SWAP.__init__(self, *args, **kwargs)
    kwargs = dict(handler_class=SCGIAppHandler)
    for kwarg in ('host', 'port', 'max_children'):
        if (locals()[kwarg] is not None):
            kwargs[kwarg] = locals()[kwarg]
    scgi_server.SCGIServer(**kwargs).serve()

What's a good function header?

#Here is Python program to fix = prefix

def serve_application(application, prefix, port=None, host=None, max_children=None):
