Wikipedia explains (http://en.wikipedia.org/wiki/Duck_typing): ------------------------------------------------------------- > In computer programming with object-oriented programming languages, duck > typing > is an alternative to typing. In duck typing, an object's suitability for some > purpose is determined by the presence of certain methods and properties [...] I did use an actual 'type' check in one of my exmaples, and that was wrong. It is possible to do a "duck-type check" with a `hasattr(other, 'items')`. I don't use Counter myself -- I'll try and find some real-world examples. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22766> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
