title: Appending an integer to dictionary keys, python
body: <p>I have a python dictionary with several keys.</p>
  <p>Example:</p>
  <p><code>dicOut = dict(list(zip(keys, values)))</code></p>
  <p><code>for i in keys:</code>
  <code>print(i)</code></p>
  <p>out:</p>
  <ul>
  <li>Trees</li>
  <li>Cars</li>
  <li>People</li>
  <li>.... x n keys</li>
  </ul>
  <p>I wish to assign a number in front.</p>
  <ul>
  <li>
  <ol>
  <li>Trees</li>
  </ol>
  </li>
  <li>
  <ol start="2">
  <li>Cars</li>
  </ol>
  </li>
  <li>
  <ol start="3">
  <li>People</li>
  </ol>
  </li>
  <li>
  <ol start="4">
  <li>.... x n keys</li>
  </ol>
  </li>
  </ul>
  <p>How do I make the for loop&quot;</p>
  <p>so far:</p>
  <pre><code> k = len(keys)
   x = range (1,k+1)
   for j in x:
    for k in keys:
       n= j, '-', k
       print(n)
  </code></pre>
  <p>However it print all e.g. 3 keys 3 time. How to stop it at just e.g. e distinct keys.</p>
