self 实例方法 ↙↙↙

class Gitee:def __repr__(self):    # self 声明实例方法return "Gitee登录"class Ding:def __repr__(self):return "Ding登录"# 当打印实例对象的时候，打印的结果就是__repr__的返回值

@classmethod 类方法 ↙↙↙ 

class Book:def __init__(self, title):self.title = title# 声明类方法@classmethoddef create(cls, title):book = cls(title)return bookif __name__ == '__main__':book1 = Book('python')print(book1.title)        # pythonbook2 = Book.create('python2')print(book2.title)        # python2

@staticmethod 静态方法 ↙↙↙ 

# 简单工厂
class SimpleFactory:# 产品@staticmethoddef product(name):if name == "Gitee":return Gitee()else:return Ding()if __name__ == '__main__':product = SimpleFactory.product("Gitee")print(product)        # Gitee登录print(Gitee())        # Gitee登录

抽象方法 @abstractmethod

目的：父类声明func()方法  继承类必须重写func()方法 ↙↙↙

# 抽象工厂模式
from abc import ABCMeta, abstractmethod# 声明元类
class TestMeta(metaclass=ABCMeta):def __init__(self):self.a = 1@abstractmethoddef func(self):pass

第一种：super() 调父类

第二种：TestMeta 调父类 ↙↙↙

class TestOne(TestMeta):def __init__(self):super().__init__()  # 声明父类.init之后 不会覆盖父类init原有属性# TestMeta.__init__()self.b = 2# TestMeta重写抽象方法（@abstractmethod声明的抽象方法必须重写，不然报错）def func(self):print('马可波罗')a = TestOne()
print(a.a)  # 输出父类TestMeta    a属性的值    1
print(a.b)  # 输出TestOne    b属性的值    2

（子类）Git三方登录方法  在视图Git三方登录中调用： 实例化Gitee类调用get方法即可生成用户token
