It would be great if you could do something like @async def longComputation(): <code> token = longComputation() token.registerCallback(callback_function) # alternative, polling while not token.finished(): doSomethingElse() if token.finished(): result = token.result() Or to call a non-async routine asynchronously def longComputation() <code> token = … Read more

Do they do the same thing, or are different? If so, which one is used for what? I want to write a program that … Read more

They use a different syntax, and differ in some details, but it seems very un-pythonic to me to have 2 functions that … Read more

I couldn’t find any information about how asyncio is actually implemented, and what makes I/O asynchronous. I was trying to read the source … Read more
