Is there a portable way to get the current username in Python?

Question

Is there a portable way to get the current user\'s username in Python (i.e., one that works under both Linux and Windows, at least). It would work like os.getuid

Answer 1

Using only standard python libs:

from os import environ,getcwd
getUser = lambda: environ["USERNAME"] if "C:" in getcwd() else environ["USER"]
user = getUser()

Works on Windows, Mac or Linux

Alternatively, you could remove one line with an immediate invocation:

from os import environ,getcwd
user = (lambda: environ["USERNAME"] if "C:" in getcwd() else environ["USER"])()
