python list next index
What you see is the interpreter echoing back the return value of next() in addition to i being printed each iteration: >>> a = iter(list(range(10))) >>> for i in a: ... ,y = (i for i,v in enumerate(l) if is_odd(v)) x1 = next(y) x2 = next(y) ... to know that no such value was found --- the list.index() function would throw ValueError here.
