title: Pandas DataFrame to List of Lists
body: <p>It's easy to turn a list of lists into a pandas dataframe:</p>
  
  <pre><code>import pandas as pd
  df = pd.DataFrame([[1,2,3],[3,4,5]])
  </code></pre>
  
  <p>But how do I turn df back into a list of lists?</p>
  
  <pre><code>lol = df.what_to_do_now?
  print lol
  # [[1,2,3],[3,4,5]]
  </code></pre>
