title: Spyder does not show lists and arrays in variable explorer
body: <p>i don't really know why, but Spyder is not able to show lists or arrays in the variable explorer anymore. Do you have the same problem, any fixes? I have that problem on two computers.</p>
  
  <p>Example:</p>
  
  <pre><code>CSV = []
  for x in os.listdir(location):
      if x.split(".")[-1] =="CSV":
          CSV.append(location+x)
  CSV = np.array(CSV)
  </code></pre>
  
  <p>Thank you very much!</p>
