title: Creating tuples with np.zero
body: <p>I might just be too stupid, but I need a fast version for this:</p>
  
  <pre><code>for i in range(0,4):
      c.append((0,0,0))
  
  out: [(0,0,0),(0,0,0),(0,0,0),(0,0,0)] 
  </code></pre>
  
  <p>I want to create a <code>zero filled tuple</code> in the <strong><code>shape of (xL,)</code></strong> with x being the amount of <code>(0,0,0)'s</code> ... I now do have three working solutions, none of them includes <code>np.zero</code></p>
