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

What is a portable way (e.g. for Linux and Windows) to get the current user’s username? Something similar to os.getuid() would be nice:

>>> os.getuid()
42

>>> os.getusername()
'slartibartfast'

The pwd module works for Unix only. Some people suggest that getting the username under Windows can be complicated in certain circumstances (e.g., running as a Windows service).

Look at getpass module

import getpass
getpass.getuser()
'kostya'

Availability: Unix, Windows

p.s. Per comment below “this function looks at the values of various environment variables to determine the user name. Therefore, this function should not be relied on for access control purposes (or possibly any other purpose, since it allows any user to impersonate any other).“
