If I do a <code>print(dir(pychromecast))</code> at a Python prompt, I get the list at the bottom of this message. Which of the methods are supposed to work? Because some do, like <code>pychromecast.get_device_status()</code> But others like <code>_get_chromecast_from_host</code> or <code>get_chromecasts</code>throw an attribute error like:

Is it that I am doing/understanding something fundamentally wrong? Does the
_ before the name play into it?

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc.. You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like __init__, __call__, __str__ etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
