Solve the following python programming problem given the following code:
@ with_sitl 
def test_mavlink(connpath) : 
    vehicle = connect (connpath) 
    out = MAVConnection ('udpin:localhost:15668') 
    vehicle._handler.pipe (out) 
    out.start () 
    vehicle2 = connect ('udpout:localhost:15668') 
    result = { 
        'success' : False, 
} 
    @ vehicle2.on_attribute ('location') 
    def callback(* args) : 
        result ['success'] = True 
i = 20 
    while ((not vehicle2 ['success']) and (i > 0)) : 
        time.sleep (1) 
assert result ['success'] 

    
    

    Fix the buggy line: while ((not vehicle2 ['success']) and (i > 0)) :
