Yeah, he wants to single-step it. A regular for loop is equivalent to calling next() lots of times, and you can manually call next(). Common usage: Skip a header row before iterating over the rest of a file. So how do you do the same thing with an async iterator? I'm not sure there's a way, currently. That's the question. Of course, you can always do this: async for x in aiter: break as an equivalent to "x = next(aiter)", but that's just stupid :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
