New submission from Jonathan Crall <erote...@gmail.com>:
I first noticed this when testing xdoctest on Python 3.9, and then again when using IPython. I was finally able to generate a minimal working example in Python itself. The following code: python -c "print(eval(compile('[i for i in range(3)]', mode='eval', filename='foo', flags=221184)))" produces [0, 1, 2] in Python <= 3.8, but in 3.9 it produces: <coroutine object <module> at 0x7fa336d40ec0> <string>:1: RuntimeWarning: coroutine '<module>' was never awaited RuntimeWarning: Enable tracemalloc to get the object allocation traceback Is this an intended change? I can't find any notes in the CHANGELOG that seem to correspond to it. ---------- components: Interpreter Core messages: 367651 nosy: Jonathan Crall priority: normal severity: normal status: open title: Python 3.9 eval on list comprehension sometimes returns coroutines versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40438> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
