Listing available com ports with Python

This is the code I use.

Successfully tested on Windows 8.1 x64, Windows 10 x64, Mac OS X 10.9.x / 10.10.x / 10.11.x and Ubuntu 14.04 / 14.10 / 15.04 / 15.10 with both Python 2 and Python 3.

import sysimport globimport serialdef serial_ports():    """ Lists serial port names        :raises EnvironmentError:            On unsupported or unknown platforms        :returns:            A list of the serial ports available on the system    """    if sys.platform.startswith('win'):        ports = ['COM%s' % (i + 1) for i in range(256)]    elif sys.platform.startswith('linux') or sys.platform.startswith('cygwin'):        # this excludes your current terminal "/dev/tty"        ports = glob.glob('/dev/tty[A-Za-z]*')    elif sys.platform.startswith('darwin'):        ports = glob.glob('/dev/tty.*')    else:        raise EnvironmentError('Unsupported platform')    result = []    for port in ports:        try:            s = serial.Serial(port)            s.close()            result.append(port)        except (OSError, serial.SerialException):            pass    return resultif __name__ == '__main__':    print(serial_ports())

Basically mentioned this in pyserial documentationhttps://pyserial.readthedocs.io/en/latest/tools.html#module-serial.tools.list_ports

import serial.tools.list_portsports = serial.tools.list_ports.comports()for port, desc, hwid in sorted(ports):        print("{}: {} [{}]".format(port, desc, hwid))

Result :

COM1: Communications Port (COM1) [ACPI\PNP0501\1]

COM7: MediaTek USB Port (COM7) [USB VID:PID=0E8D:0003 SER=6 LOCATION=1-2.1]

You can use:

python -c "import serial.tools.list_ports;print serial.tools.list_ports.comports()"

Filter by know port:python -c "import serial.tools.list_ports;print [port for port in serial.tools.list_ports.comports() if port[2] != 'n/a']"
