animation with ipythonblocks

animation

1. using clear_output function

   1. demo import

       from ipythonblocks import BlockGrid
       import time
       from IPython.display import clear_output
      

   2. demo time.sleep()

       grid = BlockGrid(3, 3)
       previous_block = None
      
       for block in grid:
           clear_output()
           block.green = 255
      
           if previous_block:
               previous_block.green = 0
      
           grid.show()
      
           previous_block = block
           time.sleep(0.2)
      

   3. demo BlockGrid.animate()

       grid = BlockGrid(3, 3)
       previous_block = None
      
       for block in grid.animate():
           block.green = 255
      
           if previous_block:
               previous_block.green = 0
      
           previous_block = block
      

   4. demo BlockGrid.flash()

       grid = BlockGrid(3, 3)
      
       previous_block = None
      
       indices = [[(0, 0), (0, 2), (2, 0), (2, 2)], [(0, 1), (1, 0), (1, 2), (2, 1)]] * 10
      
       for ind in indices:
           for i in ind:
               grid[i[0], i[1]].green = 255
      		    
           grid.flash(display_time=0.1)
      		    
           for i in ind:
               grid[i[0], i[1]].green = 0
      
       grid.show()
