title: Python: How to Remove mouseCallback in OpenCV
body: <p>With OpenCV and Python, is there any way to remove the mouse callback set with <code>cv2.setMouseCallback(window_name, function_name)</code>? Passing <code>None</code> for the function name gives;</p>
  
  <p><code>TypeError: on_mouse must be callable</code></p>
  
  <p>This is a duplicate of <a href="https://stackoverflow.com/questions/20278574/how-to-remove-mousecallback-in-opencv">How to Remove mouseCallback in OpenCV</a>, but for Python, not C++.</p>
  
  <p>Thanks,</p>
