Question

I have written the following Python code:

#!/usr/bin/python
# -*- coding: utf-8 -*-

import os, glob

path = '/home/my/path'
for infile in glob.glob( os.path.join(path, '*.png') ):
    print infile

Now I get this:

/home/my/path/output0352.png
/home/my/path/output0005.png
/home/my/path/output0137.png
/home/my/path/output0202.png
/home/my/path/output0023.png
/home/my/path/output0048.png

/home/my/path/output0295.png
/home/my/path/output0131.png
/home/my/path/output0208.png
/home/my/path/output0194.png

In which way is it ordered?

To clarify: I am not interested in ordering – I know sorted. I want to know in which order it comes by default.

It might help you to get my ls -l output:

It is not ordered by filename or size.

Other links: glob, ls

Answer 1

It is probably not sorted at all and uses the order at which entries appear in the filesystem, i.e. the one you get when using ls -U. (At least on my machine this produces the same order as listing glob matches).
