title: Iterating over dictionary containing array objects in python
body: <p>So I'm trying to iterate over a dictionary object in python and all I'm getting is list out of index error. Here is what my list looks like - </p>
  
  <pre><code>test_list = {"1":[{"1":[{"a":"100","b":"200"}],"2":[{"a":"300","b":"400"}]}]}
  </code></pre>
  
  <p>And here is the code - </p>
  
  <pre><code>for counter in range(len(test_list)):
              print test_list['1'][counter]
  </code></pre>
  
  <p>Any idea why am I getting that error?</p>
  
  <p>EDIT: I want to access all of a &amp; b elements in test_list</p>
