Python defines what the initialization method of the class is.

Today, the editor will share with you the relevant knowledge of what the initialization method of the python definition class is, the content is detailed, and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your 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 initialization method of class class MyClass:#. The first parameter is self of the object itself, and the second parameter is the parameter def _ init__ (self, name): print (name) # that must be passed when instantiation. You only need to pass the name parameter to c = MyClass ("eraser") what Python is mainly used for:

1. Web development

2. Data science research

3. Web crawler

4. Embedded application development

5. Game development

6. Desktop application development.
