用于在Python中通过字典循环语句

Question

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))

我想要for循环执行的操作是一次获取一项，然后获取相应的类型和位置。 现在，我坚持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.

Answer 1

假设您的shops字典中的每个值都是具有类型和位置的另一个字典。

您想要的可能是-

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

您可以使用str.format通过**传递字典来通过名称访问参数：

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
