Question

我喜欢Conway的生命游戏，并开始尝试用python编写它。此刻我还没有为程序的边界编写任何代码，所以我只是在寻求现在的帮助。在初始化“闪光灯”形成时我似乎遇到了麻烦。它似乎不会像它应该那样摆动，而是将自己变成一个立方体。

#File: gameoflife.py
#Description: This is a basic "life" simulation that follows three distinct rules:
#1.Any live cell with fewer than two live neighbours dies
#2.Any live cell with two or three live neighbours lives
#3.Any live cell with more than three live neighbours dies
#4.Any dead cell with exactly three live neighbours becomes a live cell
#A neighbor is deemed as any cell directly horizantal/vertical/diagonal
#meaning there are 9 neighbors to a cell at any time

def initial(D,M,win):    
    #Creates the white board background      
    for i in range (11):
        m = [] # rectangle list
        for j in range (11):
            rec = Rectangle(Point(6 + 4 * i, 6 + 4 * j), Point(10 + 4 * i, 10 + 4 * j))

            D[i][j] = 0
            rec.setFill("white")
            rec.draw(win)    
            m.append(rec)
        M.append(m)


def check(x,y,D):
    #Checks all 9 adjacent neihbors to see if "alive" and checks this number
    #means the cell should stay alive(1), die(0), or if already dead come
    #back alive(2)
    counter = 0

    if D[x+1][y] == 1:
        counter += 1
    if D[x-1][y] == 1:

                        #Fills the cell black
                        M[i][j].setFill("Black")
        #Sets the main list = to the temporary list

Answer 1

您将需要交换D和C，而不只是将C分配给D.现在，D和C将在第一次迭代后引用相同的列表。

Answer 2

这是一个简单的算法，使用任意2D大小的numpy数组在python中进行Conway的生命游戏：

import numpy

# this function does all the work
def play_life(a):
    xmax, ymax = a.shape
    b = a.copy() # copy grid & Rule 2
    for x in range(xmax):
        for y in range(ymax):
            n = numpy.sum(a[max(x - 1, 0):min(x + 2, xmax), max(y - 1, 0):min(y + 2, ymax)]) - a[x, y]
            if a[x, y]:
                if n < 2 or n > 3:
                    b[x, y] = 0 # Rule 1 and 3
            elif n == 3:
                b[x, y] = 1 # Rule 4
    return(b)

# replace (5, 5) with the desired dimensions
life = numpy.zeros((5, 5), dtype=numpy.byte)

# place starting conditions here
life[2, 1:4] = 1 # a simple "spinner"

# now let's play
print(life)
for i in range(3):
    life = play_life(life)
    print(life)

这不是很有效，但肯定会完成工作。将print(life)替换为您喜欢的任何图形调用。
