That's pretty close to my original thoughts. But one question.
Why explicitly convert string a to an iter? The 'in' test
would work with the original string. What extra magic does
iter confer? Or are you extending reuse beyond strings?
And of course the original challenge was not for a
boolean result but a specific string result so I'd
go with:
def test(a,b):
return {True: b,
False: 'Give me something that's not useless next time.'
}[all(c in a for c in b)]
or even
def test(a,b)
return b if all(c in a for c in b) else "Give me something that's
not useless next time."
Are we there yet? :-)
