python输出电脑上所有的串口名的方法

输出电脑上所有的串口名：

import serial
import serial.tools.list_ports
from easygui import *

port_list = list(serial.tools.list_ports.comports())
if len(port_list) <= 0:
 print "The Serial port can't find!"

else:
 for i in list(port_list):

#print i[0] 仅仅输出端口号，像COM1、COM3、COM9

print i[1]

输出一个串口名：

# -*- coding: utf-8 -*

import serial
import serial.tools.list_ports

port_list = list(serial.tools.list_ports.comports())

if len(port_list) <= 0:
 print "The Serial port can't find!"

else:
 port_list_0 =list(port_list[0])

port_serial = port_list_0[0]

ser = serial.Serial(port_serial,9600,timeout = 60)

print "check which port was really used >",ser.name
