🍖 isinstance( ) 和 issubclass( ) 方法

一. isinstance(obj,cls)

• 检查对象(obj) 是否是类(cls) 实例出来的

class Foo1:
    def __init__(self):
        self.name = "派大星"

class Foo2:
    def __init__(self):
        self.name = "海绵宝宝"

f1 = Foo1()
f2 = Foo2()

print(isinstance(f1,Foo1))  # True
print(isinstance(f2,Foo1))  # False

二. issubclass(sub,super)

• 检查sub类是否是super类的派生类

class Foo1:
    def __init__(self):
        self.name = "章鱼哥"

class Bar1(Foo1):
    def run(self):
        print("快跑")

class Bar2:
    def run(self):
        print("快跑")

print(issubclass(Bar1,Foo1))  # True
print(issubclass(Bar2,Foo1))  # False
