Top Level Await in Python like in Deno
Hi all, Deno is JavaScript runtime that has very nice feature like Top Level Await, I think it would be also nice to have such feature in Python, it will make using async/await more convenient What do you think ? Share your ideas lets discuss ...

I don't know what to think because I don't know what "top level await" means to you. Can you show an example of what it would look like, how you would use it, and *why* you would use it? Can you show a simple example of a task that would be better with top level await, and why it is better? -- Steve
I mean to be able to do something like this: ```python import asyncio await asyncio.sleep(1); ```
If it's for the REPL, it's already there, you simply need to start the async REPL. $ python -m asyncio asyncio REPL 3.8.5 | packaged by conda-forge | (default, Sep 16 2020, 17:43:11) [Clang 10.0.1 ] on darwin Use "await" directly instead of "asyncio.run()". Type "help", "copyright", "credits" or "license" for more information.
import asyncio await asyncio.sleep(1)
compile and exec have a mode to allow top-level async as well if you want it programmatically, then you can `await` your code object. -- Ma On Sat, 6 Feb 2021 at 07:43, Guido van Rossum <guido@python.org> wrote:
The proposal is to add a default event loop that is always active.

It is not the same, it will work in interactive mode .... But I want to run application without interactive mode

Sorry - previous reply was sent empty. So, you probably can do with `asyncio.run`: ``` In [26]: import asyncio In [27]: asyncio.run(asyncio.sleep(2)) ``` https://docs.python.org/3/library/asyncio-task.html#asyncio.run On Wed, 24 Mar 2021 at 06:44, <redradist@gmail.com> wrote:

Yes I can, but I am taking about to use it without `asyncio.run` Whenever Python in Top-Level faces with await it will wrap calling all top level statement in async function (for example)
