Yes! I'd argue that the same can be said for Django for those either currently using or exploring the use of the heavyweight Python web framework. Take a look at Flask and build your understanding from the ground up. Anyway, at the end of the day they all have their place and IRT the Op's question: It never hurts to gain an understanding of another language/framework. There's so many amazing projects across the entire landscape that it never hurts to have even a cursory familiarity (e.g. breadth and depth being complementary).
