title: Conditional skip of code lines
body: <p>I have a <code>time_slots</code> list of sublists, which looks like this:</p>
  
  <pre><code>[[(37913.0, 0.3104248046875),
  (37917.0, 0.3106689453125),
  (37919.0, 0.31201171875)],
  [(37945.0, 0.3123779296875), (37947.0, 0.31201171875)],
  [],
  [(37977.0, 0.311279296875),
  (37979.0, 0.310791015625),
  (37981.0, 0.3106689453125)],
  [(38008.0, 0.31103515625),
  (38011.0, 0.31005859375),
  (38012.0, 0.3109130859375)],
  [],
  [(38039.0, 0.3095703125),
  (38042.0, 0.3101806640625),
  (38044.0, 0.3123779296875)],
  [],
  [],
  </code></pre>
  
  <p>I am applying a <code>for</code> loop on <code>time_slots</code> array which is like:</p>
  
  <pre><code>for y in range(0,len(time_slots)):
  
      x_points,y_points = zip(*time_slots[y])
      inrplt_func = interpolate.CubicSpline(x_points,y_points)
  </code></pre>
  
  <p>Notice that there are empty lists in <code>time_slots</code> (e.g 3rd and 6th elements). <strong>What i want to do is tuple unpacking line if list is empty</strong>
  I know i can use <code>break</code> but i don't want leave loop.</p>
