Last time, Simple Tricks looked at some built-in Python functions. This time, we look at three built-in Python container classes, tuple, list, and dict, with a focus on designing useful sub-classes based on them.
We’ll explore the built-in __new__ and __init__ methods in detail along with some of the other built-in methods that help you to create rich new types. [The reader is assumed to be familiar with the basics of object-oriented programming.]
