安装pyserial
pip install pyserial
# coding:utf-8 import serial.tools.list_ports plist = list(serial.tools.list_ports.comports()) if len(plist) <= 0: print("没有发现端口!") else: plist_0 = list(plist[0]) serialName = plist_0[0] serialFd = serial.Serial(serialName, 9600, timeout=60) print("可用端口名>>>", serialFd.name)
