title: Pick a key from a dictionary python
body: <p>go through a dictionary picking keys from it in a loop?</p>
  
  <p>For example lets say I have the following dictionary: <code>{'hello':'world', 'hi':'there'}</code>. Is there a way to <code>for</code> loop through the dictionary and print <code>hello, hi</code>? </p>
  
  <p>on a similar note is there a way to say <code>myDictionary.key[1]</code> and that will return <code>hi</code>?</p>
