Solve the following python programming problem given the following code:
def __init__(self, sink_id) : 
    self.data = StringIO () 
    self.sink_id = sink_id 
    self.struct = TidyOutputSink () 
    self.struct.sinkData = ctypes.cast (ctypes.pointer (ctypes.c_int (sink_id)), ctypes.c_void_p) 
    write_func = put_byte.data.write 
    def put_byte(sink_id, byte) : 
        write_func (byte.decode ('utf-8')) 
self.struct.putByte = PutByteType (put_byte) 
    self._as_parameter_ = ctypes.byref (self.struct) 

    
    

    Fix the buggy line: write_func = put_byte.data.write
assistant
#Here is Python program to fix the buggy line: write_func = put_byte.

write_func = self.data.write
