As for async, you are either doing async or not -- you can't even run an async def function without an event loop -- so again, it won't show up in real code newbies need to understand (at least until async becomes common practice with python...) -CHB So if you absolutely need to teach it to a beginner, it > shouldn't be difficult once they understand the difference between an > expression and a statement. > probably not, though that's a distinction that's mostly academic in the early stages of learning, it may become more critical now... again, not a huge deal, just a little bit more complexity -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov
