[Python-Dev] Show DeprecationWarning in debug mode?

Hi, I noticed that Python not only hides DeprecationWarning, but also PendingDeprecationWarning and ImportWarning by default. While I understand why we decided to hide these warnings to users for a Python compiled in release mode, why are they hidden in Python debug builds? I'm asking the questio

[Python-Dev] Python initialization and embedded Python

Hi, The CPython internals evolved during Python 3.7 cycle. I would like to know if we broke the C API or not. Nick Coghlan and Eric Snow are working on cleaning up the Python initialization with the "on going" PEP 432: https://www.python.org/dev/peps/pep-0432/ Many global variables used by the "

[Python-Dev] Clarify the compatibility policy of lib2to3.

Hi, Few days ago, I submitted a patch(https://github.com/python/cpython/pull/4417) which updates2to3 converts `operator.isCallable(obj)` to `isinstance(obj, collections.abc.Callable)`. This was Serhiy Storchaka’s idea(https://bugs.python.org/issue32046) and I agree with his idea since `callab

Re: [Python-Dev] unittest isolation and warnings

Tests are not isolated from the warnings system, so things will leak out. Your best option is to use the context manager in the warnings module to temporarily make all warnings raise exceptions and test for the exception (I'm at the airport, hence why I don't know the name of the context manager; t

[Python-Dev] unittest isolation and warnings

Hi guys, when writing tests, I suddenly discovered that unittest is not isolated to warnings. Example: One of my tests emits warnings when a certain condition is met. Instead of reporting the error immediately, it uses warnings, and at the end of the test, an error is produced if there were warni
