[Tutor] Preffered way to search posix filesystem

[Miles Stevenson]

Thanks for the advice! My problem was that the built-in Python docs in Kdevelop weren't up-to-date, and 
I had trouble finding walk() in the docs. Here is the approach that I used being a python newbie 
(improvements are welcome):

<wordwrap=OFF>

def getfiles(path):
    """Recursively search a path and generate a lit of OGG files found

    Takes a filesystem path as an argument. The path is recursively searched for
    OGG files. Returns a list of each file found (in absolute path format) with
    the first element of the list set to 'start'"""
    filelist = ['start']
    for root, dirs, files in os.walk(path):
        for name in files:
            a = os.path.join(root, name)
            if os.path.isfile(a) and fnmatch.fnmatch(a, '*.ogg'):
                filelist.append(a)
    return filelist

</wordwrap>

What is interesting is that the latest 2.4 Python docs say that walk() returns a Tuple, which is untrue. 
It returns a generator object according to type(). This had me heavily confused as to how to use 
what was returned from walk() and it took a good hour of troubleshooting to figure it out.
