pwd — The password database
This module provides access to the Unix user account and password database. It is available on all Unix versions.
Password database entries are reported as a tuple-like object, whose attributes correspond to the members of the passwd
structure (Attribute field below, see <pwd.h>
):

The uid and gid items are integers, all others are strings. KeyError

where the encrypted password is stored in a file /etc/shadow
which is not world readable. Whether the pw_passwd field contains anything useful is system-dependent. If available, the spwd
module should be used where access to the encrypted password is required.
It defines the following items:
