How python defines the initialization of a class

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.
