grp --- The group database

grp --- The group database[UNKNOWN NODE transition]

This module provides access to the Unix group database. It is available on all Unix versions.

Group database entries are reported as a tuple-like object, whose attributes correspond to the members of the group structure (Attribute field below, see <pwd.h>):

IndexAttributeMeaning
0gr_namethe name of the group
1gr_passwdthe (encrypted) group password; often empty
2gr_gidthe numerical group ID
3gr_memall the group member's user names

The gid is an integer, name and password are strings, and the member list is a list of strings. (Note that most users are not explicitly listed as members of the group they are in according to the password database. Check both databases to get complete membership information. Also note that a gr_name that starts with a + or - is likely to be a YP/NIS reference and may not be accessible via getgrnam() or getgrgid().)

It defines the following items:

grp.getgrgid(gid)

Return the group database entry for the given numeric group ID. KeyError is raised if the entry asked for cannot be found.

Deprecated since version 3.6: Since Python 3.6 the support of non-integer arguments like floats or strings in getgrgid() is deprecated.

grp.getgrnam(name)

Return the group database entry for the given group name. KeyError is raised if the entry asked for cannot be found.

grp.getgrall()

Return a list of all available group entries, in arbitrary order.
