title: How to append a vector to a matrix in python
body: <p>I want to append a vector to a matrix in python. I tried <code>append</code> or <code>concatenate</code> methods but I didn't get the answer. I was previously working with Matlab and there I used this:</p>
  
  <pre><code>m = zeros(10, 4) % define my matrix, 10x4
  v = ones(10, 1) % my vecto, 10x1
  c = [m,v] % so simple! the result is: 10x5 (the vector added as the last column)
  </code></pre>
  
  <p>How can I do that in python using numpy?</p>
