Sorry, my bad. When I created the original list I was splitting a
string in two pieces. The latter portion of the string had a newline
at the end. I had

I've got a list of strings. There are some duplicates. I want a list

mylist = ['project1' , 'project2', 'project3', 'project4', 'project1']
d = {}

cleanedlist = d.keys()
But d.keys() seems t

Thanks Bill, I read the link you sent, and I am not sure what they mean by "You cannot rely on __file__, because __file__ is not there in the py2exed main-script." can't I use _file_ in my application though? This is what I just added to my application and it seems to do the trick... is there an ex

Hi Dick,
I'm looking at the last part of the main() function:

Nice to have you around! This list is to help with
any problem you may be having with the language and how to solve certain
problems.
So, if you have specific questions, please do post
them. And be warned, no one here would like to do any homework for
you.
Enjoy you stay
