Solve the following python programming problem given the following code:
def start(self) : 
    '
        Start trapping WINCH signals and resizing the PTY.

        This method saves the previous WINCH handler so it can be restored on
        `stop()`.
        ' 
    def handle(signum, frame) : 
        if (signum == signal.SIGWINCH) : 
            self.pty.resize () 
self.original_handler = signal.signal (signal.SIGWINCH, self) 

    
    

    Fix the buggy line: self.original_handler = signal.signal (signal.SIGWINCH, self)
assistant
#Here is Python program to fix the buggy line: self.

self.original_handler = signal.signal (signal.SIGWINCH, def handle()
