Bug description:

Running the asyncio REPL with Python 3.13b1 on Windows gives

>py -3.13  -m asyncio
Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main
  File "<frozen runpy>", line 88, in _run_code
  File "C:\Users\Berry\AppData\Local\Programs\Python\Python313\Lib\asyncio\__main__.py", line 126, in <module>
    readline.set_completer(completer.complete)
    ^^^^^^^^

due to missing readline package.

Easy to fix by removing

try:
import readline # NoQA
except ImportError:
pass

and inserting import readline # NoQA before line 121:
try:
import rlcompleter
except:
pass
else:
completer = rlcompleter.Completer(console.locals)
readline.set_completer(completer.complete)
