So you see it prints out that tuple and a dictionary there. But there's another way we can get access to all the variables in a Python function without using any asterisks at all, and that's the locals function. So let's rewrite our original function definition, perform operation num1, num2, operation equals by default sum. And we're going to print the output of this locals function that's built into Python, and we can call this perform operation one comma two, and let's call the operation multiply, okay?
