[Newbie]Trouble with string method

[Sean Berry]

In order to do what you are trying here...
you would have to do something like the following.

L2 = []
for item in L:
    L2.append(string.lower(item))

then do your sort
L2.sort

This way, you are applying the lower to a string, and not the list.
If you do not need to change the case of all characters to lower, then
you should use my suggestion from my previous post.

If you do need to lower case all characters... then try what I have above.
