Solve the following python programming problem given the following code:
@ classmethod 
def _parse_test(cls, buf) : 
    def __test_pkt_from_json(test) : 
        data = eval ('/'.join (test)) 
        data.serialize () 
        return six.binary_type (data.data) 
target_dp = DummyDatapath (OfTester.target_ver) 
    tester_dp = DummyDatapath (OfTester.tester_ver) 
    description = buf.get (KEY_DESC) 
    prerequisite = [] 
    if (KEY_PREREQ not in buf) : 
        raise ValueError (('a test requires a "%s" block' % KEY_PREREQ)) 
for flow in buf [KEY_PREREQ] : 
        msg = ofproto_parser.ofp_msg_from_jsondict (target_dp, flow) 
        msg.serialize () 
        prerequisite.append (msg) 
tests = [] 
    if (KEY_TESTS not in buf) : 
        raise ValueError (('a test requires a "%s" block.' % KEY_TESTS)) 
for test in buf [KEY_TESTS] : 
        if (len (test) != 2) : 
            raise ValueError (('"%s" block requires "%s" field and one of "%s" or "%s" or "%s" field.' % (KEY_TESTS, KEY_INGRESS, KEY_EGRESS, KEY_PKT_IN, KEY_TBL_MISS))) 
test_pkt = { 
            
} 
        if (KEY_INGRESS not in test) : 
            raise ValueError (('a test requires "%s" field.' % KEY_INGRESS)) 
if isinstance (test [KEY_INGRESS], list) : 
            test_pkt [KEY_INGRESS] = __test_pkt_from_json (test [KEY_INGRESS]) 
else : 
            if isinstance (test [KEY_INGRESS], dict) : 
                test_pkt [KEY_PACKETS] = { 
                    'packet_text' : test [KEY_INGRESS] [KEY_PACKETS] [KEY_DATA], 
                    'packet_binary' : __test_pkt_from_json (test [KEY_INGRESS] [KEY_PACKETS] [KEY_DATA]),

                    KEY_PKTPS : test [KEY_INGRESS] [KEY_PACKETS].get (KEY_PKTPS, DEFAULT_PKTPS), 
                    'randomize' : (True in [(line.find ('randint') != (- 1)) for line in test [KEY_INGRESS] [KEY_PACKETS] [KEY_DATA]]), 
} 
else : 
                raise ValueError (('invalid format: "%s" field' % KEY_INGRESS)) 
if (KEY_EGRESS in test) : 
            if...

    
    

    Fix the buggy line: 'OFPMatch' : test [KEY_MATCH] ,
assistant
#Here is Python program to find ('randint') != (- 1)) for line in test [KEY_INGRESS] [KEY_PACKETS] [KEY_DATA]]),
