加载中…python3 判断元素是否在列表中
(2018-04-13 17:18:46)| 分类： Python3 |
判断元素是否在列表中，可以通过in或者not in来判断。
代码实例：
fruit_basket = ['apple', 'banana', 'orange']
fruit = 'watermelon'
if fruit in fruit_basket:
print(fruit
+ ", in the fruit_basket.")
else:
print(fruit
+ ", not in the fruit basket.")
fruit = 'orange'
if fruit not in fruit_basket:
print(fruit + ", not in the fruit basket.")
else:
print(fruit + ", in the
fruit_basket.")
输出：
watermelon, not in the fruit basket.
orange, in the fruit_basket.
代码实例：
