title: Generating tuples from DataFrame row elements
body: <p>I hope this is not me doing something stupid programmatically.</p>
  
  <p>I have a one row Dataframe with numerical Values:</p>
  
  <pre><code>df1                          A            B            C          D
  
   01-02-2003T00:00:00         5.0         7.0          2.0        4.0   ....
  </code></pre>
  
  <p>I want to generate a list of tuples based on the values in the dataframe.  I do the following:</p>
  
  <pre><code>my_array = numpy.array(df1)
  </code></pre>
  
  <p>which give me: </p>
  
  <pre><code>           0            1            2          3
  
   0        5.0          7.0          2.0        4.0   ....
  </code></pre>
  
  <p>Then I do:</p>
  
  <pre><code> my_tuple_of_tuples =  tuple((0.5*x, 1.5*x) for x in my_array)
  </code></pre>
  
  <p>I expect this:</p>
  
  <pre><code>((2.5,7.5),(3.5,10.5),(1.0,3.0),(2.0,6.0))
  </code></pre>
  
  <p>but I get this:</p>
  
  <pre><code>((2.5,3.5,1.0,2.0),(7.5,10.5,3.0,6.0)) 
  </code></pre>
  
  <p>What am I doing wrong?</p>
