[issue40117] __round__ doesn't behave well with return NotImplemented
New submission from Hameer Abbasi : Minimal reproducer: >>> class A: ... def __round__(self): ... return NotImplemented ... >>> round(A()) NotImplemented Should give a TypeError. This can be useful when deciding, for example, if a given a.dtype implements round based on the dtype -- components: Interpreter Core messages: 365323 nosy: Hameer Abbasi priority: normal severity: normal status: open title: __round__ doesn't behave well with return NotImplemented versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 ___ Python tracker <https://bugs.python.org/issue40117> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue36178] type.__init__ called instead of cls.__init__ when inheriting from type.
New submission from Hameer Abbasi :
I may be completely misunderstanding here, but: here's a reproducible example:
class MyMeta(type):
def __new__(cls, *args, **kwargs):
print('__new__', *args, **kwargs)
super().__new__(cls, *args, **kwargs)
def __init__(self, a):
print('__init__', *args, **kwargs)
super().__init__(*args, **kwargs)
class A(metaclass=MyMeta):
pass
MyMeta('A', (), {'__module__': '__main__', '__qualname__': 'A'})
Output:
__new__ A () {'__module__': '__main__', '__qualname__': 'A'}
__new__ A () {'__module__': '__main__', '__qualname__': 'A'}
Is this by design?

Hameer Abbasi added the comment: Ah, I wasn't aware I had to return... The bug was deliberate to show that not even a different signature makes a difference. ;) -- ___ Python tracker <https://bugs.python.org/issue36178> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue36359] contextvars documentation unclear on thread-locality
New submission from Hameer Abbasi : The documentation here: https://docs.python.org/3/library/contextvars.html does not mention anything about context-variables being thread-local or not. It should definitely make that more clear. I was told by Freenode user njs (I strongly suspect its Nathaniel J. Smith) that they are. -- assignee: docs@python components: Documentation messages: 338322 nosy: Hameer Abbasi2, docs@python, yselivanov priority: normal severity: normal status: open title: contextvars documentation unclear on thread-locality type: enhancement versions: Python 3.7, Python 3.8 ___ Python tracker <https://bugs.python.org/issue36359> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
