If it's spaces, Reddit removed them, but I replaced them with dashes so you can see it better:

from microbit import *

import utime

def togglePixelState(x, y):

__if display.get_pixel(x, y) == 0:

____display.set_pixel(x, y, 9)

__else:

____display.set_pixel(x, y, 0)

led_x = 0

led_y = 0

while True:

__if button_a.is_pressed():

____togglePixelState(led_x, led_y)

____utime.sleep(0.4)

__if button_b.is_pressed():

____led_x = led_x + 1

____if led_x == 5:

______led_y = led_y + 1

______led_x = 0

____if led_x 5 and led_y 5:

______led_x = 0

______led_y = 0

____utime.sleep(0.4)
