Antoine Pitrou added the comment: You misread that paragraph:
""" For instance, to execute the statement x += y, where x is an instance of a class that has an __iadd__() method, x.__iadd__(y) is called.""" This is the present case, and the case of most mutable containers. """If x is an instance of a class that does not define a __iadd__() method, x.__add__(y) and y.__radd__(x) are considered, as with the evaluation of x + y.""" This is not the present case. ---------- _______________________________________ 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
