61-自定义异常

def set_age(name,age):
    if not 0 < age < 80:
        raise ValueError('年龄超过范围')  # 自主决定触发什么样的异常
    print("%s is %d years old" % (name,age))

def set_age2(name,age):
    assert 0 < age < 80, '年龄超过范围'  # 断言异常
    print("%s is %d years old" % (name,age))

if __name__ == '__main__':
    set_age('xiaoming',50)
    set_age2('xiaohong', 90)

结果输出：
