If you're expecting "exactly one result", then surely it should be an error to receive more than one result? Rather than ask for "any" result and ignoring any unexpected extra items, I think it would be better to have a helper function that verifies you have got exactly one result.
Why do you need a helper function? Simply write:
x, = db.query("SELECT blah...")
and you'll get a ValueError if there isn't exactly one item in the sequence.
Amen! Georg -- Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out.
