title: How to multiply sequence by non-int of type 'float'?
body: <p>I am trying to multiply an array of arrays by a certain number. That it, multiply each value of each array by the same constant. I was trying to do it this way:</p>
  
  <pre><code>&gt;&gt;&gt; a = [[1,1],[1,1]]
  &gt;&gt;&gt; b = [[1,1],[1,1]]
  &gt;&gt;&gt; c = [[1,1],[1,1]]
  &gt;&gt;&gt; 0.1 * [a,b,c]
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  TypeError: can't multiply sequence by non-int of type 'float'
  </code></pre>
  
  <p>Is there a smarter 'Numpier' way to do it rather than creating a for loop?</p>
