I&#x27;d argue that a rich type system shifts logic errors into syntax error. An easy example is time arithmetic. Adding seconds to minutes can be problematic. If you have proper types defined (in any language, pythons types do fine for this) then you need to confirm that addition of minutes and seconds is correct in one place, and the type system will guarantee it&#x27;s done correctly throughout your code.<p>A richer type system allows you to move more logic into type system.
