title: Spyder is throwing "assert sys.modules[modname] is not old_mod" when running pythoncom code
body: <p><strong>Edited:</strong> If I run the following code two times via spyder, it gives me an error the second time I run it, the first time it always works:</p>
  
  <pre><code>import pythoncom
  
  if __name__ == '__main__':
      print("hallo")
  </code></pre>
  
  <p>This is the error:</p>
  
  <pre><code>File "C:\Users\Oliver\AppData\Local\Programs\Python\Python36-32\lib\site-packages\win32\lib\pywintypes.py", line 129, in __import_pywin32_system_module__
      assert sys.modules[modname] is not old_mod
  </code></pre>
  
  <p>When I restart the kernel, it works again. Also if I run it directly using python, it always works.</p>
