I think it`s 1-liner.

Nice. BTW, you can make it even shorter replacing <pre class='brush: python'>set.union(*..., set())</pre> by <pre class='brush: python'>set().union(*...)</pre>

Yeah I thought about that a few days ago on <a href="https://py.checkio.org/mission/light-up/">another problem</a>. <pre class='brush: python'>set.union(...) requires at least one argument some_set.union(...) don't requires any argument </pre>
