.. I found a kind of mnemonic to help me remember when the "else" part happens: I think of it not as "for ... else" but as "break ... else" -- saying it this way makes it clear to me that the break goes with the else. "If this condition inside the loop is true, break. ... else if we didn't break, do this other thing after the loop."

Note that since break itself is typically guarded by an "if" as in

for i in x: ... if cond(i): break ... else: ...

you can match the "else" above to the "if" inside the loop.
