Solve the following python programming problem given the following code:
def count(self, page_size = 10, vtimeout = 10, callback = None) : 
    "
        Utility function to count the number of messages in a queue.
        Note: This function now calls GetQueueAttributes to obtain
        an 'approximate' count of the number of messages in a queue.
        " 
    def counted(a) : 
        if callable (callback) : 
            callback (int (a ['ApproximateNumberOfMessages'])) 
self.get_attributes ('ApproximateNumberOfMessages', callback = self) 

    
    

    Fix the buggy line: self.get_attributes ('ApproximateNumberOfMessages', callback = self)

#Here is Python program to fix the buggy line: self.

self.get_attributes ('ApproximateNumberOfMessages', callback = def counted()
