Martin v. Löwis added the comment: I find Stefan's proposed equality confusing. Why is it based on memcmp? Either it compares memory (i.e. internal representations), or it compares abstract values. If it compares abstract values, then it shouldn't be a requirement that the format strings are equal in any sense. Instead, the resulting values should be equal. So I propose this definition:
v == w iff v.shape() == w.shape() and v.tolist() == w.tolist() if either operation fails with an exception, the objects are not equal Of course, the implementation doesn't need to literally call tolist; instead, behaving as-if it had been called is fine. However, as time is running out, I would actually propose this to be the implementation in 3.3. In addition, I would propose to support the 'u' and 'w' codes in tolist, to resolve what Victor says the actual issue is. I'm -1 on a definition that involves equivalence of format strings. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15573> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
