I think this would be better written as:

def addstock_info(addstock):
        print "Getting Stockinfo data from Yahoo"
        for i in addstock:
                results=quotes.findQuotes(i)
                # Of course, we are throwing away all but the last
                # result, but thats what the original code did, too

I think this is what you need:

>>> l=['IBM','EK','MO','UTX']
>>> l
['IBM', 'EK', 'MO', 'UTX']
>>> s=','.join(l)
>>> s
'IBM,EK,MO,UTX'
>>> 
and pass s to quotes.findQuotes
