for unWantedItem in directoryList[,,-1]:

for unWantedItem in directoryList[,,-1]:
^
SyntaxError: invalid syntax
I understand what you are saying to do, and it makes sense, but I'm not sure how to impliment it.

"for" goes thru the list accessing item[0], item[1], item[2], etc. Let's
say "for" is on item[1] and you remove item[1]. All the subsequent items
"move left", so item[2] becomes item[1], item[3] becomes item[2], etc.
"for" then steps to item[2], skipping the original item[2].
There are several ways around this. The easiest is to process the list
backwards: for unWantedItem in directoryList[,,-1]:
