I do it often enough to want this.
Most of the time it's just a single condition which disturbs the coherence of the loop body.
When I first started writing Python this struck me as an inconsistency... if it's useful in comprehensions, why not regular loops? I realize comprehensions are all about construction of the list itself, but the parallel still exists.
Also feels similar to guard statements. I'd love to see Python gain more pattern matching and destructuring features because they are wonderful in Erlang/Elixir.
but it's usually fine to just have a condition on a separate line. (I do use ": continue" rather than making it two lines.)
FWIW, code I write or review would mandate this be two lines followed by a blank line, so 3 total. I require any abrupt change or termination in the current flow of control to be followed by a blank line so the reader clearly sees the possible jump (continue, break, and return especially).
