( https://docs.python.org/2/reference/compound_stmts.html) "Else" becomes sort of "part of the loop". Thus if you break out of the loop, "else" would not be executed. However, if no break occurs "else" part would be executed. It might be a rare case where it's needed. (I cannot think of any), but to achieve exactly the same functionality in Pascal either of two options should be used. 1) make an extra check if break occurred. breakflag:=false; while cond do if someothercond then begin breakflag : =true; break; end; if not breakflag then while_else_code 2) use goto! :) label postElseLabel while cond do if someothercond then begin goto postElseLabel end; while_else_code :postElseLabel thanks, Dmitry
