title: iterate through nested JSON object and get values with Python
body: <p>I am using Python; and I need to iterate through JSON objects and retrieve nested values. A snippet of my data follows:</p>
  
  <pre><code> "bills": [
  {
    "url": "http:\/\/maplight.org\/us-congress\/bill\/110-hr-195\/233677",
    "jurisdiction": "us",
    "session": "110",
    "prefix": "H",
    "number": "195",
    "measure": "H.R. 195 (110\u003csup\u003eth\u003c\/sup\u003e)",
    "topic": "Seniors' Health Care Freedom Act of 2007",
    "last_update": "2011-08-29T20:47:44Z",
    "organizations": [
      {
        "organization_id": "22973",
        "name": "National Health Federation",
        "disposition": "support",
        "citation": "The National Health Federation (n.d.). \u003ca href=\"http:\/\/www.thenhf.com\/government_affairs_federal.html\"\u003e\u003ccite\u003e Federal Legislation on Consumer Health\u003c\/cite\u003e\u003c\/a\u003e. Retrieved August 6, 2008, from The National Health Federation.",
        "catcode": "J3000"
      },
      {
        "organization_id": "27059",
        "name": "A Christian Perspective on Health Issues",
        "disposition": "support",
        "citation": "A Christian Perspective on Health Issues (n.d.). \u003ca href=\"http:\/\/www.acpohi.ws\/page1.html\"\u003e\u003ccite\u003ePart E - Conclusion\u003c\/cite\u003e\u003c\/a\u003e. Retrieved August 6, 2008, from .",
        "catcode": "X7000"
      },
      {
        "organization_id": "27351",
        "name": "Natural Health Roundtable",
        "disposition": "support",
        "citation": "Natural Health Roundtable (n.d.). \u003ca href=\"http:\/\/naturalhealthroundtable.com\/reform_agenda\"\u003e\u003ccite\u003eNatural Health Roundtable SUPPORTS the following bills\u003c\/cite\u003e\u003c\/a\u003e. Retrieved August 6, 2008, from Natural Health Roundtable.",
        "catcode": "J3000"
      }
    ]
  },
  </code></pre>
  
  <p>I need to go through each object in "bills" and get "session", "prefix", etc. and I also need go through each "organizations" and get "name", "disposition", etc. I have the following code:</p>
  
  <pre><code>import csv
  import json
  
  path = 'E:/Thesis/thesis_get_data'
  
  with open (path + "/" + 'maplightdata110congress.json',"r") as f:
  data = json.load(f)
  a = data['bills']
  b = data['bills'][0]["prefix"]
  c = data['bills'][0]["number"]
  
  h = data['bills'][0]['organizations'][0]
  e = data['bills'][0]['organizations'][0]['name']
  f = data['bills'][0]['organizations'][0]['catcode']
  g = data['bills'][0]['organizations'][0]['catcode']
  
  for i in a:
      for index in e:
            print ('name')
  </code></pre>
  
  <p>and it returns the string 'name' a bunch of times.</p>
  
  <p>Suggestions? </p>
