How Can I Retrieve the Current Username Cross-Platform in Python?

Cross-Platform Username Retrieval in Python

In Python, retrieving the current user's username should be a straightforward task. However, the standard library doesn't provide a cross-platform solution similar to the widely used os.getuid().

Specifically, the pwd module is limited to Unix systems, leaving developers searching for an alternative that works seamlessly across multiple platforms.

Introducing the getpass Module

Fortunately, the getpass module offers a solution that fits the bill. This module provides the getuser() function, which retrieves the username on both Unix and Windows systems:

import getpass
getpass.getuser()

Note on Security

It's important to note that the getpass module relies on environment variables to determine the username. Consequently, this function shouldn't be solely used for access control purposes, as it allows users to impersonate others.
