title: how to take sum of two 1-D array(column vector)
body: <p>I wanted to add two 5 X 1 column vector. But I am getting error:
  Invalid syntax</p>
  
  <pre><code>def sumg():
      w = np.ones((5,1))
      s = 1
      g=0
      b = np.random.rand(5,1)
      g = b + np.multiply(s,w)
   return(g)
  </code></pre>
  
  <p>I expect the output to return  b+s*w</p>
