I agree that modifying tuple is bad idea in general case. But in case of constants, in-place modify is the easiest approach. Our purpose is "merging" constant. On the other hand, "build new tuple and replace old tuple" approach makes two same constant tuples. If old tuple is referenced from somewhere, we fail to "merging". So I don't think we need to follow the general principle unless it reduces code. FYI, we have similar in-place editing for interning already. https://github.com/python/cpython/blob/master/Objects/codeobject.c#L47-L95 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34100> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
