Python-数据分割和提取

Question

I am using the Twitch API and i am having issues in understanding how to extract data from it.

I call the API and this is the sort of response i get:

"name":"user1", "game":"game1","name":"user2", "game":"game2"

I know i will need to use some .split() 's but i cannot work out how as each time i try i get a blank output.

The data i need is the user1 , game1 , user2 , game2

This data is repeated several times and i cannot find out how to extract this data from the mass of other data given.

Any links or advice will be grateful, i cannot find any reference to large data extraction like this

EDIT

After being advised it was json data i edited the code to parse it appropriately. But i keep getting the error: AttributeError: 'unicode' object has no attribute 'get'

Here is the code:

import urllib2
import json

url = "https://api.twitch.tv/kraken/channels/'Mychannel'/follows/"

if __name__ == "__main__":
    req = urllib2.Request(url)
    opener = urllib2.build_opener()
    f = opener.open(req)
    json = json.load (f)

    for item in json:
        print item.get('name')

Any suggestions to why this error is occurring?

Answer 1

The response is json data; use the json module to parse it.

Answer 2

assuming you are receiving a string back, such that:

>>> a = '"name":"user1", "game":"game1","name":"user2", "game":"game2"'
>>> a
'"name":"user1", "game":"game1","name":"user2", "game":"game2"'

You can get your first split by doing a split by the ","

>>> mlist = a.split(",")
>>> mlist
['"name":"user1"', ' "game":"game1"', '"name":"user2"', ' "game":"game2"']

Now you can access the data of each element by looping:

>>> for e in mlist:
    print("Data:", e.split(":")[1])

('Data:', '"user1"')
('Data:', '"game1"')
('Data:', '"user2"')
('Data:', '"game2"')
