Question

I understand the example in the Python lesson when I read it line by line, but if I look away and try to write a recursive function myself, I freeze. I can write loops fine. The moment a function calls itself my brain stops tracking where the values are.

Try adding print statements inside the function and run it with a very small input, like countdown(3). Watch the order of the output. You will see each call pause, wait for the smaller call, then finish on the way back up. Then write the same function as a loop. Seeing both versions side by side is what made it stop feeling like magic for me.
