Depending on exactly what format you've got, either .split(',') on
the line, or if this is insufficient look at the csv module. You'll
then need some way of turning the list of strings both of these
will give you into the mixed float/string tuple you want, which
could be somewhat tedious. Without knowing what these lines look
like, or what they represent, I can't begin to guess how you might
go about it. Actually, I can -- I'd start by considering whether a
dict might be more appropriate than a tuple and use csv.DictReader.
