The section on object-oriented programming explains features of the language that facilitate common programming patterns.After developing the key Python language features, the book moves on to third-party modules that are foundational for effective data analysis, starting with Numpy. The book develops ...

You’ll explore this later on in this tutorial. You can also use decorators to modify Python functions, classes, or methods. This is yet another technique so that you can program functionality only once, after which it can be used from any function, class, or method that you’ve decorated...
