Inheritance is designed for code reuse and design reuseIn an inheritance relationship, an existing, well-designed class is called a parent class or base class, and a newly designed class is a subclass or a derived classDerived classes can inherit the public members of the parent class, but cannot inherit their private membersIf you need to call a method of a base class in a derived class, you can use the built-in function super () or the base class name. Method name () to implement--------------

Python is a high-level scripting language that combines explanatory, compiled, interactive, and object-oriented. Python 's design is highly readable, with English keywords often used in other languages, some punctuation in other languages, and it has a more distinctive grammatical structure than other languages. Python is an interpreted language: this means that

▲ Functional Programming Function programmingfunction when Python built-in support for a package. We can decompose complex tasks into simple tasks by splitting large pieces of code into functions through a layer of function calls, and this decomposition can be called process-oriented programming. function is the basic unit of process-oriented program design.Funct

Python has many similarities with Perl,c and the Java language. There are, however, some clear distinctions between languages. The purpose of this chapter is to allow you to quickly learn the syntax of Python. First Python program:Interactive mode Programming: The call interpreter does not pass the script file as a p

Python decorator mode and Aspect-Oriented Programming details, python aspect Let's discuss the decorator today. The decorator is a well-known design model and is often used in scenarios with cut-plane requirements. It is more classic in terms of log insertion, performance testing, and transaction processing. The decorator is an excellent design for solving such p
