Solve the following python programming problem given the following code:
def test_produce_consume(self) : 
    channel = self.c.channel () 
    producer = Producer (channel, self.e) 
    consumer1 = Consumer (channel, self.q) 
    consumer2 = Consumer (_received1, self.q2) 
    self.q2 (channel).declare () 
    for i in range (10) : 
        producer.publish ({ 
            'foo' : i, 
}, routing_key = 'test_transport_memory') 
for i in range (10) : 
        producer.publish ({ 
            'foo' : i, 
}, routing_key = 'test_transport_memory2') 
_received1 = [] 
    _received2 = [] 
    def callback1(message_data, message) : 
        _received1.append (message) 
        message.ack () 
def callback2(message_data, message) : 
        _received2.append (message) 
        message.ack () 
consumer1.register_callback (callback1) 
    consumer2.register_callback (callback2) 
    consumer1.consume () 
    consumer2.consume () 
    while 1 : 
        if ((len (_received1) + len (_received2)) == 20) : 
            break 
self.c.drain_events () 
self.assertEqual ((len (_received1) + len (_received2)), 20) 
    producer.publish ({ 
        'compressed' : True, 
}, routing_key = 'test_transport_memory', compression = 'zlib') 
    m = self.q (channel).get () 
    self.assertDictEqual (m.payload, { 
        'compressed' : True, 
}) 
    for i in range (10) : 
        producer.publish ({ 
            'foo' : i, 
}, routing_key = 'test_transport_memory') 
self.assertTrue (self.q (channel).get ()) 
    self.q (channel).delete () 
    self.q (channel).declare () 
    self.assertIsNone (self.q (channel).get ()) 
    for i in range (10) : 
        producer.publish ({ 
            'foo' : i, 
}, routing_key = 'test_transport_memory2') 
self.assertTrue (self.q2 (channel).get ()) 
    self.q2 (channel).purge () 
    self.assertIsNone (self.q2 (channel).get ()) 

    
    

    Fix the buggy line: consumer2 = Consumer (_received1, self.q2)
assistant
#Here is Python program to fix the buggy line: consumer2 = Consumer (_received1, self.

consumer2 = Consumer (channel, self.q2)
