字典和循环

Posted 2023-01-29

创建一个名为城市的字典 在你的字典中使用三个城市的名称作为键 创建一个关于每个城市的信息字典，并包括该城市所在的国家、其大约的人口和关于该城市的一个事实 每个城市的字典的键应该是类似于国家、人口和事实的东西 打印每个城市的名称和你所存储的关于它的所有信息。

我的代码。

cities=

"Egy":
    "name":"egypt",
    "capital":"cairo",
"population": "100,000",
    "fact":"civilization"
,


"leb":
    "name":"lebanon",
    "capital":"beiruit",
"population": "10,000",
    "fact":"beautiful"
,


"moroc" :
    "name":"morocco",
    "capital":"rabat",
"population": "1000,000",
    "fact":"food"



for city, city_info in cities.items():
    print ("I love "+ city+ " and here's what I know about  it: ")

for info in city_info:
    print("the full name of the country is " + city_info["name"] + " its capital is " + city_info["capital"]+
          " the number of population is "+ city_info["population"] + " the most famous fact about it is " + city_info["fact"])

我想把这两个循环一起打印出来 这样每个国家就会变成一句话(我还没学过函数)

答案

没有必要进行第二个循环，你可以简单地这样做。

for city, city_info in cities.items():
    print ("I love "+ city+ " and here's what I know about  it: the full name of the country is " + city_info["name"] + " its capital is " + city_info["capital"]+
          " the number of population is "+ city_info["population"] + " the most famous fact about it is " + city_info["fact"])

这将产生以下输出：

I love Egy and here's what I know about  it: the full name of the country is egypt its capital is cairo the number of population is 100,000 the most famous fact about it is civilization
I love leb and here's what I know about  it: the full name of the country is lebanon its capital is beiruit the number of population is 10,000 the most famous fact about it is beautiful
I love moroc and here's what I know about  it: the full name of the country is morocco its capital is rabat the number of population is 1000,000 the most famous fact about it is food
