This is how Python knows which commands to be executed as part of the if block. So this is what you'll make your code work: >>> the_world_is_flat = True >>> if the_world_is_flat: ... print("Be careful not to fall off!") ... Be careful not to fall off! The interpreter also tries to help you, it puts ... at the begging of the line (instead of >>>) which means it expect some indentation.
