我遵循的是用Java或JavaScript编写的教程，但是规则是相同的，应该可以使用，但不能使用。简化的规则应为：
if state == 0 and neighbours == 3:
nextA[i][j] = 1
elif state == 1 and (neighbours < 2 or neighbours > 3):
nextA[i][j] = 0
else:
nextA[i][j] = state
但是当我运行代码时，我很确定第一个if语句可以工作（很难理解程序的行为很奇怪）。
规则的执行是正确的，但在Conway的《人生游戏》中，您必须每转一个步骤创建一个新的空网格。必须根据当前网格中的字段和演化规则来确定新网格中的字段。
在中创建一个新的空网格draw_squares，但从函数返回新网格：
def draw_squares(win, grid, cols, rows):
# nextA = grid # <--- DELETE
nextA = make_2d_array(cols, rows) # <--- ADD
# [...]
return nextA # <-- return the new grid
使新电网当前电网通过分配新的网格通过返回draw_squares到grid：
grid = draw_squares(WIN, grid, cols, rows)
另外，邻居的计算是错误的。字段不是其自身的邻居：
def count_neighbours(grid, x, y):
neighbourCount = 0
for i in range(-1, 2):
for j in range(-1, 2):
if i != 0 or j != 0:
neighbourCount += grid[x + i][y + j]
return neighbourCount
