This article will explain in detail the example analysis of double underlining before and after names in python. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Double underscore before and after the name (e. G. init)

This usage represents a special method name in Python. In fact, this is just a convention, and for Python systems, it will ensure that it does not conflict with user-defined names. Typically, you will override these methods and implement the functions you need in them so that Python can call them. For example, when defining a class, you often override the "init" method.

Although you can also write your own special method names, do not do so.

What does python mean Python is a cross-platform, interpretive, compiled, interactive and object-oriented scripting language, originally designed to write automated scripts, and is often used to develop independent and large-scale projects as versions are constantly updated and new features are added.
