pwd — 口令数据库 ¶

---

This module provides access to the Unix user account and password database. It is available on all Unix versions.

可用性 : Unix, not WASI, not iOS.

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> ):

索引	属性	含义
0	pw_name	Login name
1	pw_passwd	Optional encrypted password
2	pw_uid	Numerical user ID
3	pw_gid	Numerical group ID
4	pw_gecos	User name or comment field
5	pw_dir	User home directory
6	pw_shell	User command interpreter

The uid and gid items are integers, all others are strings. KeyError is raised if the entry asked for cannot be found.

注意

In traditional Unix the field pw_passwd usually contains a password encrypted with a DES derived algorithm. However most modern unices use a so-called shadow password system. On those unices the pw_passwd field only contains an asterisk ( '*' ) or the letter 'x' 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.

It defines the following items:

pwd. getpwuid ( uid ) ¶

Return the password database entry for the given numeric user ID.

pwd. getpwnam ( 名称 ) ¶

Return the password database entry for the given user name.

pwd. getpwall ( ) ¶

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