getpass
--- Portable password inputThe getpass
module provides two functions:
getpass.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. stream defaults to the
controlling terminal (/dev/tty) or if that is unavailable to sys.stderr
(this argument is ignored on Windows).
If echo free input is unavailable getpass() falls back to printing
a warning message to stream and reading from sys.stdin
and
issuing a GetPassWarning
.
Changed in version 2.5: The stream parameter was added.
Changed in version 2.6: On Unix it defaults to using /dev/tty before falling back
to sys.stdin
and sys.stderr
.
Note
If you call getpass from within IDLE, the input may be done in the terminal you launched IDLE from rather than the idle window itself.
exception getpass.GetPassWarning[source]
A UserWarning
subclass issued when password input may be echoed.
getpass.getuser()[source]
Return the "login name" of the user.
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.
