主动触发异常-raise

 1 class People:
 2     def __init__(self, name, age):
 3         if not isinstance(name, str):
 4             raise TypeError('名字必须是str类型')
 5         if not isinstance(age, int):
 6             raise TypeError('年龄必须是int类型')
 7 
 8         self.name = name
 9         self.age = age
10 
11 p = People('abc', '123')
12 
13 结果为：
