我被卡住了

在Python中，字典只能保存给定键的单个值。为了解决这个问题，我们的单个值可以是包含多个值的列表。这里我们有一本叫做“衣橱”的字典，里面有衣服的种类和颜色。填空为每种颜色的每件衣服打印一行，例如：“红色衬衫”、“蓝色衬衫”等等

wardrobe = {"shirt":["red","blue","white"], "jeans":["blue","black"]}

for __:
    for __:
        print("{} {}".format(__))`

这是我写的最大值

wardrobe = {"shirt":["red","blue","white"], "jeans":["blue","black"]}
for key, value in wardrobe.items():
    for i in value:
        print("{} {}".format(value, key))
Output: 
Here is your output:
['red', 'blue', 'white'] shirt
['red', 'blue', 'white'] shirt
['red', 'blue', 'white'] shirt
['blue', 'black'] jeans
['blue', 'black'] jeans

不完全是。请记住，我们首先要遍历 字典的元素，然后通过元素 在名单上

Answer 1

在print("{} {}".format(value, key))中，请将值替换为i

Answer 2

尝试运行以下代码：

wardrobe = {"shirt":["red","blue","white"], "jeans":["blue","black"]}
for key, value in wardrobe.items():
    for i in value:
        print("{} {}".format(i, key))

Answer 3

wardrobe = {"shirt":["red","blue","white"], "jeans":["blue","black"]}
count=0
for key, value in wardrobe.items():
    for i in value:
    if count <3:
        print("{} shirt".format(i))
        count+=1
    else:
        print("{} jeans".format(i))
