The source code for glob is in the file glob.py in the standard
library. The matching is actually done in fnmatch.py, but that
shouldn't matter. The search order you're seeing is because the files
aren't listed in alphabetical order in the directory (even though you
always get your directory listing from ls in alphabetical order -- ls
sorts the list itself).
It's easy to sort the list yourself, using the sort() method on lists:
>>> L = glob.glob("*.py")
['rc.out', 'ist.out', 'soll.out']
['ist.out', 'rc.out', 'soll.out']
