You must have enough privileges to access the shadow password database (this usually means you have to be root).您必须具有足够的权限才能访问影子密码数据库（这通常意味着您必须是root用户）。

Shadow password database entries are reported as a tuple-like object, whose attributes correspond to the members of the spwd structure (Attribute field below, see <shadow.h>):影子密码数据库条目被报告为一个类似元组的对象，其属性对应于spwd结构的成员（下面的属性字段，请参阅<shadow.h>）：

Index	Attribute	Meaning
0	sp_namp	Login name
1	sp_pwdp	Encrypted password加密的密码
2	sp_lstchg	Date of last change上次更改日期
3	sp_min	Minimal number of days between changes更改之间的最小天数
4	sp_max	Maximum number of days between changes更改之间的最大天数
5	sp_warn	Number of days before password expires to warn user about it密码过期警告用户的天数

7	sp_expire	Number of days since 1970-01-01 when account expires自1970-01-01账户到期后的天数
8	sp_flag	Reserved

The sp_namp and sp_pwdp items are strings, all others are integers. sp_namp和sp_pwdp项是字符串，其他所有项都是整数。KeyError is raised if the entry asked for cannot be found.如果找不到请求的条目，则引发KeyError。

The following functions are defined:定义了以下功能：

Changed in version 3.6:版本3.6中更改： Raises a PermissionError instead of KeyError if the user doesn’t have privileges.如果用户没有权限，则引发PermissionError而不是KeyError。
