I. What is polymorphism?Polymorphism relies on the inheritance and derivation of classes, which means that functions with different functions can use the same function names, so that functions with different contents can be called with a function name.For a better understanding, take the Len () function to give an example:The function of the Len () function is to find the length of a sequence, so how does the Len () function get to the length of the sequence?The Len () function is to get the len

The previous series of posts are all about process-oriented programming, and now it's time for a wave of object-oriented explanationsFirst, IntroductionObject-oriented programming is a way of programming, using "Classes" and "objects", so object-oriented programming is actually the use of "classes" and "objects". A class is a template, the template can contain mu

() Yingpanwenjian.write ()2. Abstract class and interfaceThe essence of an abstract class is also a class, which refers to the similarity of a set of classes, including data attributes (such as All_type) and function properties (such as read, write), while the interface only emphasizes the similarity of function properties.Abstract classes are a direct concept b

using class keyword, class name generally we develop the first letter to capitalize. There are classic classes and new classes in Python, and they are not different in Python3, in which the classic class is depth-first in multiple inheritance, and the new class is breadth-f

Introspection/ReflectionWhat is reflection?Introspection, also known as reflection, shows how an object obtains its own information at run time.And in Python, reflection can make the program run with the ability to delete and change the properties or behavior of the object.If Python does not support some form of introspection, the Dir and type built-in functions
