And it has this form. …Its name is Calvin, its best friend is Hobbes, and its form is human boy. …Now along with this object I have a function I've, which is the transmogrifier. …And what this does is it takes a Calvin and transforms its form into something else. …Let's take a look at the definition of this function.…
So here it is. It accepts a Calvin object. …And then we do a little bit of type checking to make sure that the argument …is at least something like what we expect it to be. …When you're writing functions, it's a good idea to make sure that the input …that you're accepting into the function is of a structure that you expect. …Otherwise your code later could break down and you'd have a lot of debugging to do. …This is especially important if you're writing a function that could accept …
