I am curently trying to follow this Tutorial and I can’t seem to understand the following sample code:

raster_value = {

   '0%': (0, ,0, 0, 0, 0]),

   '10%': (1, ,163, 235,  153, 255]),

   '30%': (2, ,119, 195,  118, 255]),

   '50%': (3, ,85, 160, 89, 255]),

   '70%': (4, ,58, 130, 64, 255]),

   '90%': (5, ,36, 103, 44, 255])

}
