我们再来看看 if elif 使用方法的示例

age=['a','b','c','d']

if 'a' in age:
    print("you really like a!")

if 'b'in age:
    print("you really like b!")

if 'c' in age:
    print("you really like c!")

if 'e' in age:

    print("you really like e!")

输出结果如下：

you really like a

you really like b

you really like c

再看凡云阁的一段关于年龄测试的代码：

age=17
if age<2:
    price="婴儿"
elif age<4:
    price="幼儿"
elif age < 13:
    price = "儿童"
elif age<20:
    price="青少年"
elif age<65:
    price="成年人"
else:
    price="老年人"

print(F"你是{price}!")

输出结果为：

你是青少年！
