TypeError: list indices must be integers or slices, not tuple

Question

i followed a tutorial on youtube to create a snake game in python via Visual Studio code!

this is the error message i keep getting when i press a key to play the game, wondering how to fix.

Line of code causing error: self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

Answer 1

You may use the append method

Answer 2

would you mind showing the change i should make?

Answer 3

Can u send me the code snippet

Answer 4

Of u r question

Answer 5

def move(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()

keys = pygame.key.get_pressed()

for key in keys:
if keys[pygame.KEY_LEFT]:
self.dirnx = -1
self.dirny = 0
self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

elif keys[pygame.KEY_RIGHT]:
self.dirnx = 1
self.dirny = 0
self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

elif keys[pygame.KEY_UP]:
self.dirnx = 0
self.dirny = -1
self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

elif keys[pygame.K_DOWN]:
self.dirnx = 0
self.dirny = 1
self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

Answer 6

self.turns.append(self.dirnx)
self.turns.append(self.dirny)

Answer 7

so the code should look like:

for key in keys:
if keys[pygame.KEY_LEFT]:
self.dirnx = -1
self.dirny = 0
self.turns.append[self.head.pos[:]] = [self.dirnx, self.dirny]

Answer 8

append is a method so it will consist of the '()'
And u current program also going wrong

Answer 9

Plz be checked with the append function

Answer 11

I made the adjustments you suggested, my game window is not closing any more when I press the key to play.

Now i assume i need to do something else within the Def Main() Call to accommodate for the changes i just made

Answer 12

def move(self, dirnx, dirny):
self.dirnx = dirnx
self.dirny = dirny
self.pos = (self.pos[0] + self.dirnx, self.pos[1] + self.dirny)

this is the move code

Answer 13

def main():
global width, rows, s, snack
width = 500
rows = 20
win = pygame.display.set_mode((width, width))
s = snake((255,0,0), (10,10))
snack = cube(randomSnack(rows, s), color=(0,255,0))
flag = True

clock = pygame.time.Clock()

while flag:
pygame.time.delay(50)
clock.tick(10)
s.move()
redrawWindow(win)
if s.body[0].pos == snack.pos:
s.addCube()
snack = cube(randomSnack(rows, s), color= (0,255,0))

for x in range(len(s.body)):
if s.body[x].pos in list(map(lambda z:z.pos, s.body[x+1:])):
print('Score: ', len(s.body))
message_box("You Lost", "Play Again")
s.reset((10,10))
break

this is the main() call

Answer 14

I think ur quite function is not working

Answer 15

explain please. do you want me to share the code with you? i can send it via email if you would like.

either way i appreciate your help

Answer 16

import sys
def move(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.display.quite()
pygame.quit()
#sys.exit()

If pygame.display.quite() not work u can use sys.exit()

Answer 17

No please don't send me the whole code now because I'm so busy for my upcoming board exams😂😂
