In python, a_list.sort() sorts the list in place and returns None

>>>a_list = [4, 3, 5, 2, 1]
>>>r = a_list.sort()
>>>r
>>>a_list
[1, 2, 3, 4, 5]
>>>


so you would probably want ...

def gen_list(somedir):
    l = os.listdir(somedir)
    l.sort()
    return l


My understanding is that in python2.4 lists will have a sorted() method
which will return the list sorted ...  or maybe it will be a builtin like 
...
s = sorted(a_list)
