How To Add Serial Port Tool In Visual StudioNarrow Results

I am searching for a simple method to list all available com port on a PC.
I have found this method but it is Windows-specific: Listing serial (COM) ports on Windows?
I am using Python 3 with pySerial on a Windows 7 PC.
I have found in the pySerial API (http://pyserial.sourceforge.net/pyserial_api.html) a function
serial.tools.list_ports.comports() that lists com ports (exactly what I want).
But it seems that it doesn't work. When my USB to COM gateway is connected to the PC (I see the COM5 in the Device Manager), this COM port isn't included in the list returned by
list_ports.comports() . Instead I only get COM4 which seems to be connected to a modem (I don't see it in the COM&LPT section of Device Manager)!
Do you know why it doesn't work? Have you got another solution which is not system specific?

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.

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']'

A possible refinement to Thomas's excellent answer is to have Linux and possibly OSX also try to open ports and return only those which could be opened. This is because Linux, at least, lists a boatload of ports as files in /dev/ which aren't connected to anything. If you're running in a terminal, /dev/tty is the terminal in which you're working and opening and closing it can goof up your command line, so the glob is designed to not do that. Code:
This modification to Thomas's code has been tested on Ubuntu 14.04 only.

refinement on moylop260's answer:
This lists the ports that exist in hardware, including ones that are in use. A whole lot more information exists in the list, per the pyserial tools documentation

Basically mentioned this in pyserial documentationhttps://pyserial.readthedocs.io/en/latest/tools.html#module-serial.tools.list_ports
Result :
COM1: Communications Port (COM1) [ACPIPNP05011]
COM7: MediaTek USB Port (COM7) [USB VID:PID=0E8D:0003 SER=6 LOCATION=1-2.1]

Several options are available:
Call QueryDosDevice with a NULL lpDeviceName to list all DOS devices. Then use CreateFile and GetCommConfig with each device name in turn to figure out whether it's a serial port.
Pc clone ex lite software downloads. Call SetupDiGetClassDevs with a ClassGuid of GUID_DEVINTERFACE_COMPORT.
WMI is also available to C/C++ programs.
There's some conversation on the win32 newsgroup and a CodeProject, er, project.

Please, try this code:
first of all, you need to import package for serial port communication,so:
then you create the list of all the serial ports currently available:
Windows Serial Communication Software
and then, walking along whole list, you can for example print port names:
This is just an example how to get the list of ports and print their names, but there some other options you can do with this data. Just try print different variants after
port.
