Now, that might sound a little bit weird but it's easy to understand it when you see it in action. So let's open up the example code in magiccall_start. And you can see that once again, I've got my Book class and it's already implementing the str function that we learned about earlier. And I also have some code that creates a couple of book instances with titles and authors and prices. So what I'm going to do is override the __call function that lets me treat an instance of the object, like a function and I'll define the function to take the same parameters as the init function.
