Tuple? Doesn't that give you a clue?

What you mean is: The way you have presented the strings is confusing
you, and consequently you have written a comparison that will not
work :-)

Hmmmm. That comma in there is interesting. I wonder where the
parentheses came from. What did the man mutter about a list of tuples?

Nothing. They're not there. It's all in your mind.

What is "raw output"?

That's a comparison, not output.

Step 1: Find out what you've *really* got there:

Instead of
    print 'Item: ', item, '\n', 'selName: ', selName, '\n'
do this:
    print 'item', repr(item), type(item)
    print 'selName', repr(selName), type(selName)

Step 2:
Act accordingly.

Uncle John's Crystal Balls (TM) predict that you probably need this:
    if item[0] == selName:

HTH,
