Vincent, you should also try to avoid naming your lists a 'list'. There's a
couple dozen words in Python that are reserved 'for system use':

The choice of data structure usually depends on how

David,
You are processing a text file. It is your job to treat it as a file
comprised of lists. I think what you are saying is that each line in the
text file is a list. In that case

I am trying to create a program where I open a file full of lists and process

text_file =open ("voteinp.txt","r")
lines = text_file.readlines()
