title: Matplotlib: Plotting multiple lines from a 2D list
body: <p>I am having trouble plotting multiple lines from a 2D list. 
  I currently have the below dataset.</p>
  
  <pre><code>x = np.linspace(0, 4, 5)
  y = [[0.32,1.25,2.36,3.36,3.52],[0.32,1.25,2.36,3.36,3.52]]
  </code></pre>
  
  <p>and to plot this I implemented</p>
  
  <pre><code>for i in range(len(y)):
      for x in range(len(y[i])):
          plt.plot(x[x], y[I][x])
  plt.show()
  </code></pre>
  
  <p>How can I have it so that I have multiple lines in one graph thus plotting it from a 2d array?</p>
