This article will explain in detail how to define the initialization of a class 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.

1. When the class is initialized, the method _ _ init__ in the class can be defined directly, it is executed when the instance is generated, and the methods in the class are very different from ordinary functions.

2. A method in a class must contain a keyword self, that is, instance itself.

This keyword can be any variable name, but you usually use self.

Example

Declare a class and add initialization methods to the class.

# define the class class MyClass:# initialization method. The first parameter is the self of the object itself, and the second parameter is the call to the class def _ _ init__ (self, name): print (name) # that must be passed when instantiating. Just pass the name parameter and c = MyClass ("Eraser"). This article on "how python defines the initialization of a class" ends here. Hope that the above content can be helpful to you, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
