title: Create a Dataframe with lists of different sizes
body: <p>Changed to explain it better:</p>
  
  <pre><code>A = ['one',None,None,None]
  B = [None,'two',None,None],
  C = [None,None,'three','Four']
  </code></pre>
  
  <p>If i create a Dataframe I would get:</p>
  
  <pre><code>df = pd.DataFrame({'A': A,
                     'B':B,
                     'C':C
  })
  df     
         A    B       C
  0   one     None    None
  1   None    two     None
  2   None    None    three
  3   None    None    Four
  </code></pre>
  
  <p>But I want a DataFrame similar to the Expected Output below
  Expected Output:</p>
  
  <pre><code>       A    B       C
  0   one     two     three
  1   None    None    four
  </code></pre>
