This will give spaces between every word...

How about a less readable version which actually works <wink>:

   print ''.join([x+y for (x,y) in zip('test', 'dust')])

Yes... Those were the days <wink>

A version with spacing (like yours) which is a bit more readable (than
my previous one) would be:

    for firstLetter, secondLetter in zip(firstWord, secondWord):
        print firstLetter, secondLetter,

One without the spaces could be:

    result = ''
    for a, b in zip('test', 'dust'):
        result += a+b
    print result

Yeah... I think I like that one. (Although using a list and then doing
a join on that would probably be more efficient...)
