Python: How to get domain\username for logged in user

Question

In Python how do I get the logged in username in the domain\username format. The following just get username:

import getpass
import os

print(os.getlogin())
print(getpass.getuser())

Solution 1

Here you go :

import os
domain = os.environ['userdomain']
print(domain)

(But i see that this doest give the FQDN, but only the NetBIOS name)

Solution 2

If you have pywin32 installed, you can call the corresponding Windows function:

import win32api
win32api.GetUserNameEx(win32api.NameSamCompatible)

Check out this MSDN page for other possible parameters and outputs.

Solution 3

Should work in Python 2 and 3

import getpass
import platform

print(getpass.getuser()) #username
print(platform.node()) #hostname

Domainname here represent the Active Directory (or Windows NT for dinosaurs...) domain. It can be different from the host name.

[leancz]

getpass.getuser() + '\\' + os.environ['userdnsdomain']

[Robben_Ford_Fan_boy]

That returns the domain name of the Computer

This returns the logon session user name, which should also be available as the %USERNAME% and %USERDOMAIN% environment variables. This name almost always agrees with the user SID in the process access token, except the 3 common service accounts (i.e. SYSTEM, LOCAL SERVICE, and NETWORK SERVICE) get logged on as the machine name followed by a dollar sign (e.g. "SPAMBOX$"). That may surprise you if you're running as a service using one of those accounts.
