Stefan Behnel added the comment: 1) that's a regex test, so it just looks for the text. I only extended it to include the object it's supposed to test for. It's not actually related to my changes, but I considered it the right thing to do. I used "42.*is not" in order to allow for alternative spellings like "'42' is not...".
2) "raise ... from None" is the official way to explicitly drop the exception context from a newly raised exception. Otherwise, you'd get two exceptions in this case: a TypeError (as main exception) and an AttributeError (as its context), which I do not consider helpful here as it bloats the output for an otherwise simple error. For 99% of the use cases, it won't matter which attribute was missing. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17159> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
