title: Create class instance in python from list as attributes
body: <p>So I have an object:</p>
  
  <pre><code>class Particle(object):
      def __init__(self, x, y, vx, vy, ax, ay):
          self._x = int(x)
          self._y = int(y)
          self._vx = int(vx)
          self._vy = int(vy)
          self._ax = int(ax)
          self._ay = int(ay)
          # ...
  </code></pre>
  
  <p>I want to create an instance of that object from a list of numbers. How would I do that? <code>Particle(list)</code> doesn't work because it only inputs a list, not each value in the list. Thanks so much, I am sure there is a very obvious answer.</p>
