Getting name of windows computer running python sc

Question

Basically, I have a couple Windows computers on my network that will be running a python script. A different set of configuration options should be used in the script depending on which computer is running this script.

How would I get that computer name in the python script?

Let's say the script was running on a computer named DARK-TOWER, I'd like to write something like this:

>>> python.library.get_computer_name()
'DARK-TOWER'

Is there a standard or third party library I can use?

Answer 1

From https://mail.python.org/pipermail/python-list/2006-April/397494.html

import os
os.getenv('COMPUTERNAME')

Answer 2

It turns out there are three options (including the two already answered earlier):

>>> import platform
>>> import socket
>>> import os
>>> platform.node()
'DARK-TOWER'
>>> socket.gethostname()
'DARK-TOWER'
>>> os.environ['COMPUTERNAME']
'DARK-TOWER'

Answer 3

As Eric Carr said you could use these three variants.

I prefer using them together:

def getpcname():
    n1 = platform.node()
    n2 = socket.gethostname()
    n3 = os.environ["COMPUTERNAME"]
    if n1 == n2 == n3:
        return n1
    elif n1 == n2:
        return n1
    elif n1 == n3:
        return n1
    elif n2 == n3:
        return n2
    else:
        raise Exception("Computernames are not equal to each other")

I prefer it when developing cross patform applications to be sure ;)

Answer 4

Since the python scrips are for sure running on a windows system, you should use the Win32 API GetComputerName or GetComputerNameEx

You can get the fully qualified DNS name, or NETBIOS name, or a variety of different things.

import win32api
win32api.GetComputerName()

>>'MYNAME'

Or:

import win32api
WIN32_ComputerNameDnsHostname = 1 
win32api.GetComputerNameEx(WIN32_ComputerNameDnsHostname)

>> u'MYNAME'

Answer 5

I bet gethostname will work beautifully.

Answer 6

import socket
socket.gethostname()
