title: Python star symbol in a loop
body: <p>I am using CPython and I saw in one example file with a star symbol.
  Could you give an explanation what in this context the <code>*</code> symbol means?
  Here the <code>pointsets</code> is a <code>numpy array</code> that comes from <code>pybind11</code>, because it is an output of C++ code.</p>
  <p>Does the <code>Point(*point)</code> has something to do with the pointers in C++?</p>
  <pre><code>polylines = []
  for points in pointsets:
      points = [Point(*point) for point in points]
      polyline = Polyline(points)
      polylines.append(polyline)
  </code></pre>
