python擷取作業系統的使用者名稱

函數：

getpass.getuser()
解釋：

Return the “login name” of the user. Availability: Unix, Windows.

This function checks the environment variables LOGNAME, USER, LNAME and USERNAME, in order, and returns the value of the first one which is set to a non-empty string. If none are set, the login name from the password database is returned on systems which support the pwd module, otherwise, an exception is raised.

代碼如下：

import getpass
getpass.getuser()
