When we are on subject of loops... I'd love to have 'else' block for loops that runs when the loop had zero iterations.

- fuzztester 2y agoNot the same thing (although I thought it was), according to the Python docs, but related: https://docs.python.org/3/reference/compound_stmts.html https://docs.python.org/3/reference/compound_stmts.html See sections 8.3, the for statement, and 8.2, the while statement.
- scotty79 2y agoYeah, `while...else` in Python does the wrong thing. Executes `else` block when the loop finished normally (not through `break`). Scala for example has a `breakable {}` block that lets you indicate where you should land after a `break` breakable { while condition { // loop body if otherCondition then break; // rest of the body } // body of pythonic else block } // you land here if you break However I have no idea how to implement the kind of `else` I described in any language without checking the condition twice.
