With the two above codes can you solve detect_loop in python pls

Moves the front node to the rear of the List. Use: source.append_front() Returns: None "un if self.is_empty(): return current_front = self.front self.front = self.front.next current_front.next = self.front self.rear = current_front def prepend_rear(self): Moves the rear node to the front of the List. Use: source.prepend_rear() Returns: None fetect_loop(self): du" Determines if the List contains a circular reference/loop. Use: circular = source. detect_loop() - Returns: circular - True if source contains a circular reference, False otherwise (bogol) \# Your code here circular = False return circular
