Good catch!

I don't understand it now either.

But I've been up since 4:30am and am too tired to try 
figuring it out just now, so maybe someone else will 
explain! :-)

>>> for c in 'abcd':
...    print (c == c in 'crab')

It definitely seems to work as I explained it but how it works is 
defeating my befuddled brain right now. I suspect it needs 
a read of the reference manual...
