title: Generate New DataFrame without NaN Values
body: <p>I've the following Dataframe:</p>
  
  <pre><code>     a    b    c    d    e
  0  NaN  2.0  NaN  4.0  5.0
  1  NaN  2.0  3.0  NaN  5.0
  2  1.0  NaN  3.0  4.0  NaN
  3  1.0  2.0  NaN  4.0  NaN
  4  NaN  2.0  NaN  4.0  5.0
  </code></pre>
  
  <p>What I try to to is to generate a new Dataframe without the NaN values.
  There are always the same number of NaN Values in a row.</p>
  
  <p>The final Dataframe should look like this:</p>
  
  <pre><code>   x  y  z
  0  2  4  5
  1  2  3  5
  2  1  3  4
  3  1  2  4
  4  2  4  5
  </code></pre>
  
  <p>Does someone know an easy way to do this?
  Any help is appreciated.</p>
