How to check if entry is file or folder using Python's standard library zipfile?

Question

I have a zip file and I need to check if a file is a folder or a file without extracting them. I could check it using file_size property of infolist if it is 0 but this is the same for a file with 0 size. So it is not useful.

I looked on the ZIP specification but that didn't helped much either.

Is there some reason not to use `os.path.isfile(path)` and `os.path.isdir(path)`? — Francesco Montesano, Mar 07 '13 at 09:43
@FrancescoMontesano I have a very good reason I don't want to extract the file — Eduard Florinescu, Mar 07 '13 at 09:46

How about checking if the filename ends with /?

can we use `os.sep` instead of `/`? – Babu Mar 07 '13 at 10:10

@Babu according to the ZIP file specification "All slashes MUST be forward slashes". So no :) – robertklep Mar 07 '13 at 10:30
