Built-in functions

Python comes with a lot of built-in functions. They are available anywhere, and you can get a list of them by inspecting the builtins module with dir(__builtins__), or by going to the official Python documentation. Unfortunately, we don't have the room to go through all of them here. We've already seen some of them, such as any, bin, bool, divmod, filter, float, getattr, id, int, len, list, min, print, set, tuple, type, and zip, but there are many more, which you should read about at least once. Get familiar with them, experiment, write a small piece of code for each of them, and make sure you have them at your fingertips so that you can use them when needed.

You can find a list of built-in functions in the official documentation, here: https://docs.python.org/3/library/functions.html.
