gh-122858: Deprecate asyncio.iscoroutinefunction

[Wulian233]

Same inspect.iscoroutinefunction, we don't need two different functions to do the same thing.

• Issue: Deprecate asyncio.iscoroutinefunction #122858

[Wulian233]

After my many fix, maybe it is normal for the Docs workflow to fail because the deprecated function asyncio.iscoroutinefunctiondoes not have a corresponding document page introduction

But I don't know how to solve this problem. Delete whatnew/3.14.rst: func: iscoroutinefunctiondoes?

(Solved)

Please, use at least one test that ensures that the function is deprecated (which does not ignore the warnings).

[Wulian233]

This is the function that test this function c1f2743 If not have @ignore_warnings(category=DeprecationWarning) this will cause the workflow test to fail (DeprecationWarning). Do you mean to add some kind of tip below, without causing failure?

@ignore_warnings(category=DeprecationWarning)
def test_iscoroutinefunction(self):
    print("asyncio.iscoroutinefunction is deprecated, use inspect.iscoroutinefunction() instead")
    def fn(): 
      ...

(Sorry, I may not be familiar with it)
