The :mod:`getpass` module provides two functions:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
.. function:: getpass([prompt[, stream]])
|
|
|
|
|
|
|
|
|
|
Prompt the user for a password without echoing. The user is prompted using the
|
|
|
|
|
string *prompt*, which defaults to ``'Password: '``. On Unix, the prompt is
|
|
|
|
|
written to the file-like object *stream*, which defaults to ``sys.stdout`` (this
|
|
|
|
|
argument is ignored on Windows).
|
|
|
|
|
|
|
|
|
|
Availability: Macintosh, Unix, Windows.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
.. function:: getuser()
|
|
|
|
|
|
|
|
|
|
Return the "login name" of the user. Availability: Unix, Windows.
|
|
|
|
|
|
|
|
|
|
This function checks the environment variables :envvar:`LOGNAME`,
|
|
|
|
|
:envvar:`USER`, :envvar:`LNAME` and :envvar:`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 :mod:`pwd` module, otherwise, an exception is raised.
