Deprecate asyncio.iscoroutinefunction #122858
Description
Activity
Looks like an duplicate of #94912
No it isn't, in this issue we are just deprecating it not making an alias.
Reacted by Kirill Podoprigora and Wulian233If you get the deprecation error and want to support Python < 3.12, you may need to still use
asyncio.iscoroutinefunctionconditionally for backward compatibility because before #94050 merged into 3.12 (and only some 3.10 and 3.11 releases) the functions hadn't been equivalentif sys.version_info >= (3, 12): iscoroutinefunction = inspect.iscoroutinefunction else: iscoroutinefunction = asyncio.iscoroutinefunction

asyncio.iscoroutinefunctionshould be deprecated in favor ofinspect.iscoroutinefunction, we don't need two different functions to do the same thing. I propose to deprecateasyncio.iscoroutinefunctionbecause IMO these introspection functions don't belong toasynciobut more toinspectmodule. It will be deprecated in Python 3.14 and scheduled for removal in Python 3.16.Linked PRs
