You can use <a href="http://docs.python.org/library/os.html#os.access" rel="nofollow">os.access(path, mode)</a> to know if operations requiring permissions specified by mode are possible on file specified by path or not. P.S. This will not work for files being accessed over the network. You can use <a href="http://docs.python.org/library/os.html#os.stat" rel="nofollow">os.stat</a> This is the right way to get all the information. However it is a more costly call and hence, you should try and get all the info in one call . To interpret the results, you can use the <a href="http://docs.python.org/library/stat.html" rel="nofollow">stat</a> module</p></li> </ol>
