code: def show():
      """Display pending images.
  
      Launch the event loop of the current GUI plugin, and display all
      pending images, queued via `imshow`. This is required when using
      `imshow` from non-interactive scripts.
  
      A call to `show` will block execution of code until all windows
      have been closed.

      >>> rng = np.random.default_rng()
      >>> for i in range(4):
      ...     ax_im = io.imshow(rng.random((50, 50)))
      >>> io.show() # doctest: +SKIP
