我一直在嘗試將 self.Arduino 從 GetData 類繼承到 GUI 類。所以為了做到這一點，我簡單地添加了這行代碼。class GUI(QMainWindow, Ui_MainWindow, GetData):我以為它會繼承 self.Arduino 但它沒有。顯然我做錯了什么，但我不明白是什么。這是我的代碼class GetData(QThread):    ChangedData = pyqtSignal(float, float, float, float)    def __init__(self, parent=None):        QThread.__init__(self, parent)        arduino_ports = [  # automatically searches for an Arduino and selects the port it's on            p.device            for p in serial.tools.list_ports.comports()            if 'Arduino' in p.description        ]        if not arduino_ports:            raise IOError("No Arduino found - is it plugged in? If so, restart computer.")        if len(arduino_ports) > 1:            warnings.warn('Multiple Arduinos found - using the first')        self.Arduino = serial.Serial(arduino_ports[0], 9600, timeout=1)    def __del__(self):  # part of the standard format of a QThread        self.wait()    def run(self):  # also a required QThread func tion, the working part        import time        self.Arduino.close()        self.Arduino.open()        self.Arduino.flush()        self.Arduino.reset_input_buffer()        start_time = time.time()        while True:            while self.Arduino.inWaiting() == 0:                pass            try:                data = self.Arduino.readline()                dataarray = data.decode().rstrip().split(',')                self.Arduino.reset_input_buffer()                Pwm = round(float(dataarray[0]), 3)                Distance = round(float(dataarray[1]), 3)                ArduinoTime = round(float(dataarray[2]), 3)                RunTime = round(time.time() - start_time, 3)                print(Pwm, 'Pulse', ",", Distance, 'CM', ",", ArduinoTime, "Millis", ",", RunTime, "Time Elasped")                self.ChangedData.emit(Pwm, Distance, ArduinoTime , RunTime)            except (KeyboardInterrupt, SystemExit, IndexError, ValueError):
