Question

我需要一个解决方案如何在python脚本中打印出文件权限。我们的想法是将shell命令$: ls -l传递给一个python脚本，我将从那里用＆＃34;其他解释＆＃34;打印出这些行。例如

-rwxrwxr-x

另外的解释是：

Owner of the file has reading rights, writing right, but doesn't have execution rights. Group has reading rights, writing right and execution rights.

那么，除了涵盖谁拥有什么权利的所有可能情况之外，除了用if条件检查每个案例之外，还有更简单的方法吗？

以下是一些可以帮助您入门的代码。

我们首先创建一个名为modes的列表，其中包含具有权限的人员和他们拥有的权限类型的所有组合。然后我们并行循环模式字符串和我们的modes列表，如果模式字符串在该位置没有modes，则从-抓取相关组合。

modes = [(who, kind) for who in ('user', 'group', 'others') 
    for kind in ('read', 'write', 'execute')]

def explain_modestring(modestring):
    return ', '.join([' can '.join(t) 
        for c, t in zip(modestring[1:], modes) if c != '-'])

for s in ('-rwxrwxrwx', '-rwxr-xr--', '-r--------'):
    print(s, explain_modestring(s))

<强>输出

-rwxrwxrwx user can read, user can write, user can execute, group can read, group can write, group can execute, others can read, others can write, others can execute
-rwxr-xr-- user can read, user can write, user can execute, group can read, group can execute, others can read
-r-------- user can read
