# 1.背景 #

最近在使用陀螺仪获取待测对象的姿态信息，用到了串口通信，使用python非常的方便；  
python3(3.6.8)需要安装的关于串口的三方包：

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ pyserial

用到的相关方法：

import serial.tools.list_ports
    ports_list = list(serial.tools.list_ports.comports())

# 2.代码 #

#TS_pyserial.py
    import sys
    print ("Python Version {}".format(str(sys.version).replace('\n', '')))
    #Python Version 3.6.8 |Anaconda, Inc.| (default, Feb 21 2019, 18:30:04) [MSC v.1916 64 bit (AMD64)]
    
    import serial.tools.list_ports
    
    '''Function design, single entry single exit principle'''
    def scan_ports_info(Handle_print=0):
        ''''''
        ports_list = list(serial.tools.list_ports.comports())
        if Handle_print:
            print("[info]ports number:",len(ports_list))
    
        if len(ports_list) <= 0:
            print("The Serial port can't find!")
        else:
            for i in range(len(ports_list)):
                port_list = list(ports_list[i])
                port_serialName = port_list[0]
                if Handle_print:
                    print('\n[info]port list', port_list)
                    print('[info]port serial Name',port_serialName)
        return ports_list
    if __name__=="__main__":
        ports=scan_ports_info(Handle_print=0)
        for i in range(len(ports)):
            port_list = list(ports[i])
            port_serialName = port_list[0]
            print('\n[info]port list', port_list)
            print('[info]port serial Name', port_serialName)
