Solve the following python programming problem given the following code:
def decorate_class(self, klass, * args) : 
    setup = getattr (klass, 'setUp', None) 
    teardown = getattr (klass, 'tearDown', None) 
    if (not setup) : 
        setattr (klass, 'setUp', wrap_setup.start) 
else : 
        def wrap_setup(* args) : 
            self.start () 
            setup (* args) 
setattr (klass, setup.__name__, wrap_setup) 
if (not teardown) : 
        setattr (klass, 'tearDown', self.stop) 
else : 
        def wrap_teardown(* args) : 
            self.stop () 
            teardown (* args) 
setattr (klass, teardown.__name__, wrap_teardown) 
return klass 

    
    

    Fix the buggy line: setattr (klass, 'setUp', wrap_setup.start)
