here is my code but i guess the problem is mainly in my python

import random
import curses
screen=curses.initscr()

# Initialize curses
screen = curses.initscr()


curses.curs_set(0)
screen_height,screen_width= screen.getmaxyx()
window=curses.newwin(screen_height,screen_width,0,0)
window.keypad(1) #allow window to take input
window.timeout(100)
snk_x=screen_width//4
snk_y=screen_height//2
snake=[
    [snk_y,snk_x],
    [snk_y,snk_x-1],
    [snk_y,snk_x-2],
]
food=[screen_width//2,screen_height//2]
window.addch(food[0],food[1],curses.ACS_PI)
key=curses.KEY_RIGHT
while True:
    next_key=window.getch()
    key=key if next_key==-1 else next_key
    if snake[0][0]in [screen_height,0] or snake[0][1] in [screen_width,0] or snake[0] in snake[1:]:
        break
    new_head=[snake[0][0],snake[0][1]]
    if key==curses.KEY_UP:
        new_head[0]-= 1
    if key==curses.KEY_DOWN:
         new_head[0]+= 1
    if key==curses.KEY_RIGHT:
         new_head[1]+= 1
    if key==curses.KEY_LEFT: 
          new_head[1]-= 1  
    snake.insert(0,new_head)
    if snake[0]==food:
         food=None
         while food==None:
            new_food=[
              random.randint(1,screen_width-1),
              random.randint(1,screen_height-1)
            ]
            food=new_food if new_food not in snake else None
         window.addch(food[0],food[1],curses.ACS_PI)
    else:
         tail=snake.pop()
         window.addch(tail[0],tail[1],' ')
    window.addch(snake[0][0],snake[0][1],curses.ACS_CKBOARD)

curses.endwin()
quit()

i have tried installing curses from my terminal and i tried installing python again but it didn’t work i also got to a point where it worked well but stopped at the addch function
