It really depends on what people are doing with their down. If indexing potentially missing values is common, there will be a performance impact. Also, the cost of a __repr__ varies wildly depending on the data (i.e. a collections.Counter instance has an expensive __repr__, decimal objects have computations to runs as well). >From a user point of view, a repr might be helpful or it might be >disasterously lengthy (a webpage, a giant bytearray, a long list of tuples). Personally, I would rather not do this PR which seems to have the view that the exception is an error condition as opposed to being a normal way to terminate a series of index() calls. ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30477> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
