How do I do this in Python? I only need to write a code for modification

A 2D list checker is declared as checker = [[(255,0,0), (255, 255, 255), (255,0,0), (255,255,255), (255,0,0)), [(255,255,255), (255,0,0), (255,255, 255), (255,0,0), (255,255,255)], [(255,0,0), (255, 255, 255), (255,0,0), (255,255,255), (255,0,0)]] which represents the following image. Modify checker using nested for loops so that the outcome image becomes as follows. Hint: The RGB representation of black is (0,0,0).
