Karthikeyan Singaravelan <[email protected]> added the comment:
This could sometimes make the output verbose when the arguments themselves are
tasks while including arguments in the signature in _format_coroutine.
$ cat /tmp/foo.py
import asyncio
async def foo(a, b): pass
async def main():
task = asyncio.create_task(foo(1, b=1))
task1 = asyncio.create_task(foo(1, b=task))
print(repr(task))
print(repr(task1))
asyncio.run(main())
$ python3.8 /tmp/foo.py
<Task pending name='Task-2' coro=<foo() running at /tmp/foo.py:3>>
<Task pending name='Task-3' coro=<foo() running at /tmp/foo.py:3>>
$ ./python.exe /tmp/foo.py
<Task pending name='Task-2' coro=<foo(a=1, b=1) running at /tmp/foo.py:3>>
<Task pending name='Task-3' coro=<foo(a=1, b=<Task pending name='Task-2'
coro=<foo(a=1, b=1) running at /tmp/foo.py:3>>) running at /tmp/foo.py:3>>
