动态创建class

脑子

目的: 自由选择继承的父类是哪个.
方法: 使用type()函数.

type can be used to dynamically create a class. First parameter is the class name, second are the classes to inherit from and third are the initial attributes.

示例:

class ParentA:
    def a(self):
        print('hi, A')

class ParentB:
    def b(self):
        print('hi, B')

obj = type(
        'Child_class', # class name
        (ParentA, ParentB), # parent classes
        {
            'info': lambda self: print('hi, child') 
        }
)()

obj.a()
obj.b()
obj.info()
