| I propose to add a new function sys.shutting_down() (name debatable) returning True if the interpreter is currently shutting down. This would be a function so that you can bind it and avoid having it wiped at shutdown :-) |

| For the issue #22599, I wrote a patch but then I removed my patch and reverted my changed... Here is a new patch which implements why I already wrote: add a new sys._is_finalizing() function, with a unit test. > I propose to add a new function sys.shutting_down() (name debatable) The name sounds like a function to shut down the computer or exit Python. I don't like _is_finalizing() name neither :-) My patch uses a private function which is CPython specific. Does it make sense to add a public function instead? Is it possible to implement it in any Python implementation (PyPy, IronPython, Jython, etC.)? I guess that the most dummy implementation is to always return False (Python is always running. |

| Are there other special interpreter states about which it would by helpful to know? Interpreter initializing, garbage collecting, signal handling? |

Interpreter initializing, garbage collecting, signal > handling? - interpreter initializing: user code generally isn't executed in that phase - garbage collecting: there are already garbage collection callbacks - signal handling: well... I don't see why that would be useful |

| I'm +0 for is_finalizing. There is a typo in the docstring. |

| An indirect way how to know about interpreter shutdown -- test existing of the path attribute in sys (). |

| After solving this issue we should reconsider the traceback_ignore_linecache_error.patch patch in . |

| Before committing the patch it will be good to find places in the code which will benefit from this function. And please don't forget to fix a typo in the docstring. |

The traceback and/or the linecache is a first good candidate to use this new function. We may patch more functions later if needed, I don't think that we need to address all issues right now. |

| Using the function in the stdlib can be done separately. I fixed the typo in the docstring. Thanks! |
