I know nothing and care even less (is caring a negative amount possible?) about the internal implementation of the struct module. Since Elizabeth is volunteering to do the work to make it work, will it be accepted? Subject to the usual code quality reviews, contributor agreement, etc. Are there objections to the *idea* of adding support for null terminated strings to the struct module? Does it require a PEP just to add one more format code? (Maybe it will, if the format code requires a complete re-write of the entire module.) It seems to me that if Elizabeth is willing to do the work, and somebody to review it, this would be a welcome addition to the module. It would require at least one API change: struct.calcsize won't work for formats containing null-terminated strings. But that's a minor matter. -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
