This is more than just trivially true for Python in a scripting context, too, because it doesn’t do things like type coercion that some other scripting languages do. If you want to concat an int with a string you’ll need to cast the int first, for example. It also has a bunch of list-ish and dict-ish built in types that aren’t interchangeable. You have to “worry about types” more in Python than in some of its competitors in the scripting-language space.
