问题描述
所以我试图获取用户在Twitch上关注的频道列表，
So i'm trying to fetch a list of channels that a user follows on Twitch,
我正在使用urllib2从以下位置获取数据:
I'm using urllib2 to fetch the data from:
http://api.twitch. tv/kraken/users/user/follows/channels?offset = 0& on_site = 1
但是我只想要用户遵循的频道列表，这是原始json数据的样子，我只想要每个频道的display_name，例如['Syndicate'，'Gem28daz2012']，我该怎么做?
however I only want a list of channels that the user follows, here is what the raw json data looks like, I only want the display_name from each channel e.g ['Syndicate','Gem28daz2012'], how could I do this?

推荐答案
To parse the http response body, you can use json.loads. After that you can use a list comprehesion:
display_names = [f['channel']['display_name'] for f in data['follows']]
在某些情况下使用它:
data_str = '''
{
"follows": [{
"created_at": "2016-01-15T22:43:35Z",
"_links": {
"self": "https://api.twitch.tv/kraken/users/user/follows/channels/syndicate"
},
"notifications": false,
"channel": {
"_links": {
"self": "https://api.twitch.tv/kraken/channels/syndicate",
"follows": "https://api.twitch.tv/kraken/channels/syndicate/follows",
"commercial": "https://api.twitch.tv/kraken/channels/syndicate/commercial",
