print(fruit_dictionary) Our code returns: {'Apple':'In stock','Pear':'In stock','Peach':'In stock','Banana':'In stock'} First, we declared a list calledfruitswhich stored the names we wanted to move into a dictionary. Then, we used dictionary comprehension to run through each item ...
print(shopping_list[1]) # 输出: 香蕉 - 反向索引访问 除了正向索引外,还可以使用负索引。负索引从列表的末尾开始计数,-1表示最后一个元素,-2表示倒数第二个元素,依此类推。 print(shopping_list[-1]) # 输出: 牛奶 print(shopping_list[-2]) # 输出: 面包 ...
