spwd --- The shadow password database¶

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

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

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>):

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 user doesn't have privileges.

spwd.getspall()¶

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