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.
