Isn't .format regarded superior? Or is this just a matter of taste?It has superior features, but its current implementation is muchslower and there is a HUGE body of existing code that would needconversion (a lot of that is automatable), including most uses of thelogging module. % formatting is also familiar to anyone who uses Cand C++ on a regular basis.as martin said, both will exist for a long time.-gps
