instance method
1. It can only be called through the object (the first parameter self: represents the object itself)
2. Applicable scenario: If you want to use the properties or methods of the object inside the method, you must define it as an object method
class method
1. First use @classmethod declaration
2. (The first parameter cls: represents the class itself)
3. It can be called by class or by object
4. Applicable scenarios: only class attributes or class methods are used inside the method (no need using object properties and methods), suitable for defining as class methods
static method
1. Use @staticmethod declaration first
. 2. It can be called by class or by object.
3. Applicable scenario: inside the method (neither need to use class properties and class methods nor object properties and methods), it is suitable to be defined as static method method
