To check the file permissions using python scripting

Hi,

For a particular set of files, am trying to check if they are writable. i.e., checking whether they are having permissions greater than 755.
Am able to check this using the statement:
"if (os.path.isfile(FILE_PATH) and (os.stat(FILE_PATH).st_mode & 0777) == 0777):"

But the problem here is am exactly not sure, which all are the write permissions on a file.

or, is there any other way to check if file is having permissions greater than 755,

Any help in this regard is useful.
Thanks,
Arjun

st_mode method returns a decimal value. And you're performing a "bit-wise &" with an octal number "0777".
If language is not a constraint, you may try this in a shell script:
Code:
ls -l filename | egrep "^-rwxr[-w]xr[-w]x|^-rwxrw[-x]rw[-x]"
