spwd —- The shadow password database

This module provides access to the Unix shadow password database. It isavailable on various Unix versions.

You must have enough privileges to access the shadow password database (thisusually means you have to be root).

Shadow password database entries are reported as a tuple-like object, whoseattributes correspond to the members of the spwd structure (Attribute fieldbelow, see <shadow.h>):

索引	属性	意义
0	`sp_namp`	登录名
1	`sp_pwdp`	Encrypted password
2	`sp_lstchg`	Date of last change
3	`sp_min`	Minimal number of days betweenchanges
4	`sp_max`	Maximum number of days betweenchanges
5	`sp_warn`	Number of days before passwordexpires to warn user about it
6	`sp_inact`	Number of days after passwordexpires until account isdisabled
7	`sp_expire`	Number of days since 1970-01-01when account expires
8	`sp_flag`	Reserved

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

定义了以下函数：

spwd.getspnam(name)
Return the shadow password database entry for the given user name.

在 3.6 版更改: Raises a PermissionError instead of KeyError if the userdoesn't have privileges.

spwd.getspall()
Return a list of all available shadow password database entries, in arbitraryorder.
