CSS DRY button states -

is there way this repeating same code? .button-hover { color: $button-hover-font-color; background-color: $button-hover-color; &:hover, &:focus, &:active, &:visited { color: $button-hover-font-color; background-color: $button-hover-color; } } yeah, try plain css syntax: .button-hover, .button-hover:hover, .button-hover:focus, .button-hover:active, .button-hover:visited { color: $button-hover-font-color; background-color: $button-hover-color; } or use mixin: (i know less syntax, guess it's similar whatever preprocessor using) .button-hover { color: @button-hover-font-color; background-color: @button-hover-color; &:hover, &:focus, &:active, &:visited { .button-hover(); } }

python - How to check if an iterable can be traversed again? -

consider following code: def my_fun(an_iterable): val in an_iterable: do_work(val) if some_cond(val): do_some_other_work(an_iterable) break if an_iterable list / tuple , do_some_other_work whole list again. if an_iterable iterator or generator , receive rest of items in list. how differentiate between 2 cases? want do_some_other_work receive rest of items only. there's no general way tell whether can iterate on object repeatedly. file-like objects, in particular, screw checks. fortunately, don't need check this. if want make sure do_some_other_work gets rest of items, can explicitly request iterator: def my_fun(iterable): iterable = iter(iterable) # whatever.
