推荐答案

Python没有内置使用串口的库，需要使用PySerial 库，然后，您只需从串口中逐行读取数据，看看该行是否包含数据；如果是，则意味着您的串行设备上的某些内容发生了变化(例如，按下按钮).

There is no built-in library for using serial ports in Python, you need to use the PySerial library, and then, you just read data from the serial port line by line and see if that line contains data; if it does it means that something changed on your serial device (a button press, for example).

这里有一些链接可以帮助您使用该库:
