执行API调用并存储响应
url = ‘https://api.github.com/search/repositories?q=language:python&sort=stars’
r = requests.get(url)
print("Status code: ", r.status_code)
将API响应存储在一个变量中
response_dict = r.json()
print("Total repositories: ", response_dict[‘total_count’])
研究有关仓库信息
repo_dicts = response_dict[‘items’]
print("Repositories returned: ", len(repo_dicts))
