Скачать или смотреть Single and Double Underscore Naming Conventions in Python: Conventions, Interfaces, & Constants

This is a preview of the video course, "Single and Double Underscore Naming Conventions in Python". Python has a few important naming conventions that are based on using either a single or double underscore character (_). These conventions allow you to differentiate between public and non-public names in APIs, write safe classes for subclassing purposes, avoid name clashes, and more. Following and respecting these conventions allows you to write code that looks Pythonic and consistent in the eyes of other Python developers. This skill is especially useful when you’re writing code that’s intended for other developers to work with.
