2.6 从JSON数据源导入数据

import requests
import json
url = 'https://github.com/timeline.json'

r = requests.get(url)
json_obj = r.json()#是字典
repos = set() # we want just unique urls

""" 遍历的是字典的key """
# for entry in json_obj:
# try:
# repos.add(entry)
# except KeyError as e:
# print(e)
""" 如果要遍历字典的value """
for entry in json_obj.items():
    try:
        repos.add(entry)
    except KeyError as e:
        print(e)
