Nathaniel Smith added the comment: I disagree with the stated reason for closing this, because in general, implicit context chaining doesn't care about where the exception was instantiated, only where it was raised. For example:
----- err = ValueError() try: raise KeyError except Exception: raise err ----- Prints: ----- Traceback (most recent call last): File "/tmp/bar.py", line 3, in <module> raise KeyError KeyError During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/tmp/bar.py", line 5, in <module> raise err ValueError ----- I would expect 'gen.throw(OBJ)' to be equivalent to doing 'raise OBJ' inside the generator, and raise does set __context__. ---------- nosy: +njs _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25683> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
