title: SyntaxError when defining array in python
body: <p>I wrote a program in python and when I debug my code I have some output like:</p>
  
  <pre><code>A = [[ 0.49184191  0.49216545  0.49045572  0.49120336  0.49162126  0.49127175

     0.49191334]]
  </code></pre>
  
  <p>and </p>
  
  <pre><code>Y = [[0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
    0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
    0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]]
  </code></pre>
  
  <p>And it seems no problem to execute some actions with those variables like eg: </p>
  
  <pre><code>dA = - (np.divide(Y, A) - np.divide(1 - Y, 1 - A))
  </code></pre>
  
  <p>But when I define in a separate cell some arrays for my own use:</p>
  
  <pre><code>import numpy as np
  
  m = [[4 5 6]]
  n = [[1 2 3]]
  </code></pre>
  
  <p>Then as output I have: </p>
  
  <pre><code>File "&lt;ipython-input-61-52c19e46fafb&gt;", line 3
      m = [[4 5 6]]
              ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>So why is it not possible to define m and n as I have some output like that in my other Code?</p>
