Review object-oriented programming Let's start with 30 seconds to review what OOP is all about. In object-oriented programming languages, you can define classes that are used to bundle related data and behavior together. These classes can inherit some or all of the properties of their parent classes, but they can also define their own properties (data) or methods (behavior). When the process of defining a class ends, the

There are only new classes in Python 3, no legacy classes, no designations to display, classes you define are new classes If you don't know the difference between the new class and the old one, then you don't have to know. Defined: >>> class Nothing: #定义方法和属性 pass >>> The class inside defines the method wi

Why does the Python class method need to add self as the first argument? For example, the Python class method is defined in this way: Class Charfield (Field):Description = _ ("String (up to% (max_length) s)")def __init__ (self, *args, **kwargs):Super (Charfield, self). __in
