get contents of url in python

Question

import urllib2
response = urllib2.urlopen('http://api.xyz.com')
html = response.read()

IN http://api.xyz.com

{
  "responseHeader":{
    "status":0,
    "QTime":18,
    "params":{
      "indent":"on",
      "q":"",
      "wt":"json",}},
  "response":{"numFound":7984,"start":0,"maxScore":1.0,"docs":[
      {
       "id":"21",
       "first_name":"anurag"
      },
      {
       "id":"31",
       "first_name":"abhishek"
      }
    ]
}

Problem is: this url will return json output. and i want to read that json file but it is showing error: string indices must be integers, not str.

Please include the code that throws the error, and the full traceback. — Martijn Pieters

You need to convert the JSON response to a python structure with the json library (included with Python):

import json

import urllib2
response = urllib2.urlopen('http://api.xyz.com')
data = json.load(response)  # note, no `.read()`, the library handles that

print data['response']
