【问题描述】：

我需要在字典上使用 for 循环来显示所有对应的值

shops = {

              'Starbucks': {
                  'type':'Shops & Restaurants',
                  'location':'Track 19'
               },

              'Supply-Store': {
                   'type':'Services',
                   'location':'Central Station'
               }
         }

for shop in shops:
    print(shop + " is a: " +shop.items(0))

我希望我的 for 循环做的是一次取一个项目，然后获取相应的类型和位置。现在，我一直在获取相应的类型和位置。

预期输出为：

Starbucks is a Shops & Restaurants located at Track 19.
Supply-Store is a Services located at Central Station.

【解决方案1】：

假设您的 shops 字典中的每个值都是另一个具有类型和位置的字典。

你想要的可能是-

for key,value in shops.items():
    print(key + " is a: " + value['type'] + " at : " + value['location'])

我不知道是谁否决了这个答案，但它确实有效。标记为已回答，谢谢 Sharon！

【解决方案2】：

您可以使用str.format 传递字典，使用** 按名称访问参数：

Shops = {

              'Starbucks': {
                  'type':'Shops & Restaurants',
                  'location':'Track 19'
               },

              'Supply-Store': {
                   'type':'Services',
                   'location':'Central Station'
               }
         }

for shop,v in Shops.items():
    print("{} is a {type} located at {location}".format(shop,**v))

输出：

Starbucks is a Shops & Restaurants located at  Track 19
Supply-Store is a Services located at  Central Station
