如何使用python修改文件访问控制列表？

Question

I have a script that does a whole bunch of file manipulation in python, but I'm running into trouble because I'm routinely encountering files that have ACL's set to things like "group: everyone deny delete".

For other permission issues I've used os.chmod to fix things, but can't find how to remove or modify ACL's using this, or other methods.

On macOS you can call directly chmod :

# exceptions: 
#   subprocess.CalledProcessError:
#       Command '['chmod', '-h', '-a', 'everyone deny delete', 
#                 '/Users/liviu/Music']' returned non-zero exit status 1
if 0:
    subprocess.check_call(['chmod', '-h', '-a', 'everyone deny delete', os.path.expanduser('~/Music')])

proc = subprocess.Popen(['chmod', '-h', '+a', 'everyone deny delete', os.path.expanduser('~/Music')])
proc.communicate()

I suppose there's a command line equivalent on Unix-es .
Now Windows is a different story, but you can always count on PowerShell .
