Python is fast for tiny programs. However if you have more than one team it isn't tiny. One developer can make something not tiny in a few weeks. For large programs a compiler that checks syntax, and ideally types before you run a comprehensive test suite ( which probably isn't comprehensive enough) is nearly mandatory to be maintainable. Otherwise you can never be sure you adjusted everything when you need to change an API.
