Vedran Čačić <vedgar@gmail.com> added the comment: I don't believe this. Are you seriously saying that it is ok to tell the user "object of type 'dict' has no len()" when of course it does? Please change the error message so it does not so blatantly lie. Yes, I understand the underlying issue, but the common user doesn't need to understand it, and they shouldn't be lied to. ---------- nosy: +veky _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue32500> _______________________________________
