I don't mind early returns, but I'm infamously anti "break" and "continue" statements (and all my colleagues to date have disagreed with me and have found my stance hilarious and/or infuriating). My rationale is that they turn a loop into a mutant abomination that's a loop and conditionals all mushed up together. I also can't shake this gut feeling that they're crude and antiquated control flow mechanisms, only one step away from the fiery inferno of "goto". So instead of this:

    for thing in things:
        if thing.is_yellow():
            continue

        if thing.is_rainbow():
            break

        thing.thingify()

I'll do:

    things_iter = iter(things)

    thing = next(things_iter, None)
    is_rainbow_thing_found = (
        thing.is_rainbow()
        if thing is not None
        else False
    )

    while (
        thing is not None
        and not is_rainbow_thing_found
    ):
        if not thing.is_yellow():
            thing.thingify()

        thing = next(things_iter, None)
        is_rainbow_thing_found = (
            thing.is_rainbow()
            if thing is not None
            else False
        )
