title: numpy array conversion to pairs
body: <p>I'm not sure how it is called in python i think its a pair
  Anyway I have a huge numpy array, its format is like</p>
  
  <pre><code>FFnetlayer0 =   [ 0,  243,    9,  243,   18,  243,    4,  244,   13,  244, ....etc.]
  </code></pre>
  
  <p>I need this numpy array format to be:</p>
  
  <pre><code>FFnetlayer0 =   [ (0,  243),    (9,  243),   (18,  243),    (4,  244),   (13,  244), .....]
  </code></pre>
  
  <p>Nodepairs needs to be between ( ) for building manually a neural net FFnet for python 
  I'm building a huge neural net, so i use a function to create the array but i dont get the ( ) symbols included</p>
  
  <pre><code>conec =[]
  for i in range (3):
      conec = numpy.append(conec,[(i,243),(i+9,243),(i+18,243)])
      d = 4
      conec = numpy.append(conec,[(i+d,244),(i+9+d,244),(i+18+d,244)])
      d = 7
      ...
      ..
      . 
  </code></pre>
