Just watch, learn, get a feel for it. It's easy. Previously, we saw how we could print out the arguments passed into a function using asterisk args and asterisk asterisk quargs. 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. We're going to print the output of this locals function that's built into Python. And we can call this performOperation, one comma two, and let's call the operation multiply. Okay. And what we get is a dictionary of all the variables that have been passed in, whether they're positional arguments or keyword…
