title: Mean of each element of matrices in a list
body: <p>Hello I'm new in python I couldn't solve my problem. Suppose I have a list (<code>a</code>), this list has many matricies which is the same shape. I want to get one matrix that result of mean of each elements.</p>
  <p>here is the list and its elements:</p>
  <pre><code>a[0]=[1 2 3]
  a[1]=[3 4 5]
  a[2]=[6 7 8]
  </code></pre>
  <p>Here is the desired matrix:</p>
  <pre><code> mean=[10/3 13/3 16/3]
  </code></pre>

  <p>Actually, this answer is good for me but it's for the R, not python. Sorry if I made a mistake while asking a question.</p>
