Solve the following python programming problem given the following code:
@ tape.use_cassette ('testaddremovelistmember.json') 
def testaddremovelistmember(self) : 
    params = { 
        'slug' : 'test', 
        'owner_screen_name' : username, 
        'screen_name' : 'twitter', 
} 
    def assert_list(l) : 
        self.assertEqual (l.name, params ['slug']) 
assert_list (self.api.add_list_member (** params)) 
    sleep (3) 
    assert_list (self.api.remove_list_member (** self)) 

    
    

    Fix the buggy line: assert_list (self.api.remove_list_member (** self))
