python - 诅咒蛇游戏不删除 linux 操作系统中的单元格

Question

这是我用来掌握它的 curses 教程中的代码，但即使我已经多次检查代码，它仍然没有删除旧单元格。编写代码的人使用的是 Mac，而我使用的是 Linux，这会有问题吗？

import curses
import time
import random

screen = curses.initscr()
dims = screen.getmaxyx()
def game():
    screen.nodelay(1)
    head = [1, 1]
    body = [head[:]]*5
    screen.border()
    direction = 0 # 0:right, 1:down, 2:left, 3:up
    gameover = False

    while not gameover:
        deadcell = body[-1][:]
        if deadcell not in body:
            screen.addch(deadcell[0], deadcell[1], ' ')
        screen.addch(head[0], head[1], 'X')
        if direction == 0:
            head[1] += 1
        elif direction == 2:
            head[1] -= 1
        elif direction == 1:
            head[0] += 1
        elif direction == 3:
            head[0] -= 1

        deadcell = body[-1][:]
        for z in range(len(body)-1, 0, -1):
            body[z] = body[z-1][:]

        body[0] = head[:]

        if screen.inch(head[0], head[1]) != ord(' '):
            gameover = True

        screen.move(dims[0]-1, dims[1]-1)
        screen.refresh()
        time.sleep(0.1)

game()
curses.endwin()

问题似乎在线条附近:

while not gameover:
    deadcell = body[-1][:]
    if deadcell not in body:
        screen.addch(deadcell[0], deadcell[1], ' ')

deadcell 总是在 body 中，因此永远不会清除任何单元格。

试试这个:

deadcell = body[-1][:]

while not gameover:
    if deadcell not in body:
        screen.addch(deadcell[0], deadcell[1], ' ')
