This is a function that i made for showing all empty squares neighbouring a empty square when clicked. (the program is minesweeper)
def grannar():
x = int(tomma[0])
y = int(tomma[1])
if x > 0 and y > 0:
if grid[x-1][y-1] == 0:
screen.blit(antal0, [int(((y-1) * grid_bredd)+11),int(((x-1) * grid_hojd)+69)])
tomma.extend([(x-1),(y-1)])
if x > 0:
if grid[x-1][y] == 0:
screen.blit(antal0, [int((y * grid_bredd)+11),int(((x-1) * grid_hojd)+69)])
tomma.extend([(x-1),(y)])
if x > 0 and y < 8:
if grid[x-1][y+1] == 0:
screen.blit(antal0, [int(((y+1) * grid_bredd)+11),int(((x-1) * grid_hojd)+69)])
tomma.extend([(x-1),(y+1)])
if y > 0:
if grid[x][y-1] == 0:
screen.blit(antal0, [int(((y-1) * grid_bredd)+11),int((x * grid_hojd)+69)])
tomma.extend([x,(y-1)])
if y < 8:
if grid[x][y+1] == 0:
screen.blit(antal0, [int(((y+1) * grid_bredd)+11),int((x * grid_hojd)+69)])
tomma.extend([x,(y+1)])
if y > 0 and x < 8:
if grid[x+1][y-1] == 0:
screen.blit(antal0, [int(((y-1) * grid_bredd)+11),int(((x+1) * grid_hojd)+69)])
tomma.extend([(x+1),(y-1)])
if x < 8:
if grid[x+1][y] == 0:
screen.blit(antal0, [int((y * grid_bredd)+11),int(((x+1) * grid_hojd)+69)])
tomma.extend([(x+1),y])
if y < 8 and x < 8:
if grid[x+1][y+1] == 0:
screen.blit(antal0, [int(((y+1) * grid_bredd)+11),int(((x+1) * grid_hojd)+69)])
tomma.extend([(x+1),(y+1)])
del tomma[0:2]i then call this function like this:tomma = []
if grid[rad][kolumn] == 0:
screen.blit(antal0, [int((kolumn * grid_bredd)+11),int((rad * grid_hojd)+69)])
tomma.extend([rad,kolumn])
while len(tomma) > 0:
grannar()But when i run the program and click an empty square it crashes.
