从网站获取的货币，并返回一个字典

Question

我想写从open exchange rates获取货币名单，并返回它作为一个字典的模块。我试过玩urllib模块，但我的知识是有限的。

这是我到目前为止有：

import urllib.request 
response = urllib.request.urlopen('http://openexchangerates.org/api/currencies.json') 
html = response.read() 
print(html) 

Answer 1

你有你的html变量什么是JSON字符串。只是解析它转换成一个字典：

import json 
import urllib.request 
response = urllib.request.urlopen('http://openexchangerates.org/api/currencies.json') 
html = response.read().decode("utf-8") 

my_dict = json.loads(html) 
print my_dict 

Answer 2

如果你只是想货币列出这应该这样做：

import urllib 
response = urllib.urlopen('http://openexchangerates.org/api/currencies.json') 
html = response.read() 
print(html) 

这就是我得到：
