嗨，所以我正在制作一款扫雷游戏，我有点坚持网格生成部分。这是我到目前为止的代码：
from random import randint
import pygame
def MineGen():
mineamount = 100
grid_across = 40
grid_up = 25
mine_list = []
my2dthatlist = []
numacoss = 0
for i in range (mineamount):
numacoss = randint(1,40)
my2dthatlist.append(numacoss)
numup = randint(1,25)
my2dthatlist.append(numup)
mine_list.append(my2dthatlist)
my2dthatlist = []
return mine_list
def GridGen():
grid_across = 40
grid_up = 25
GRIDD = [[0]* grid_across for i in range(grid_up)]
return GRIDD
def MineGrid(GridOutMine, mine_list):
mineplace = 0
placeX = 0
placeY = 0
for i in range(100):
mineplace = mine_list[i]
placeX = mineplace[0]
placeY = mineplace[1]
GridOutMine[placeX][placeY] = 1
print(GridOutMine)
mine_list = MineGen()
GridOutMine = GridGen()
MineGrid(GridOutMine, mine_list)
我的问题是我得到的列表索引超出了范围
GridOutMine[placeX][placeY] = 1
.part。我真的不知道这是为什么。如果您能给我一些帮助，或者只是对我的代码的一些一般性评论，我将不胜感激。
这是因为，与range不同，random.randint输出指定范围内的数字。也就是说，randint(1, 25)可以输出 25，这对于只有 25 个元素长的列表来说不是有效的索引(因为最后一个索引是 24(。
在MineGen中，你需要将randint(1, 25)更改为randint(1, 25-1)或randint(1, 24)，同样需要randint(1, 39)randint(1, 40)。我实际上建议randint(0, 24)和(0, 39)，但我不知道这是否是故意的。
关于这段代码，还有许多其他可以/应该改进的地方，但我建议你在代码工作后在 CodeReview 上而不是在这里要求这种输入(他们不会修复损坏的代码(。
编辑：
此外，您以错误的顺序索引网格。它是一个行列表(25 长(行(40 长(，因此您需要先在 Y 维度中为其编制索引，然后是 X：GridOutMine[placeY][placeX] = 1
如果您尝试为游戏构建网格，并希望在用户可以与之交互的 GUI 中显示按钮，则可能需要从以下代码开始，作为您将编写的其余代码的基本框架。
import tkinter
import functools
class MineSweep(tkinter.Frame):
@classmethod
def main(cls, width, height):
root = tkinter.Tk()
window = cls(root, width, height)
root.mainloop()
def __init__(self, master, width, height):
super().__init__(master)
self.__width = width
self.__height = height
self.__build_buttons()
self.grid()
def __build_buttons(self):
self.__buttons = []
for y in range(self.__height):
row = []
for x in range(self.__width):
button = tkinter.Button(self)
button.grid(column=x, row=y)
button['text'] = '?'
command = functools.partial(self.__push, x, y)
button['command'] = command
row.append(button)
self.__buttons.append(row)
def __push(self, x, y):
print('Column = {}nRow = {}'.format(x, y))
if __name__ == '__main__':
MineSweep.main(10, 10)
