学习日志：小程序：Conway的生命游戏解析

在学习到数组和字典时有这样一个例子：小程序：Conway的生命游戏，书上解析的不是很清楚，今天我就详细解析一下。

学习工具：Python编程快速上手-让繁琐工作自动化（第2版）、Python3.12.1、Mu编辑工具

import random, time, copy

WIDTH = 3 #数组里面共几个小列，如[(),(),(),(),......] 后面用数组a表示
HEIGHT = 3 #小列里面有几个数据，如[(*，*，*，*),(*，*，*，*),......] 后面用数组b表示
nextCells = []    #定义数组a
for x in range(WIDTH):  #从a的第0个小列开始填数据
    column = []         #定义数组b
    for y in range(HEIGHT):      #这个循环是把数据填入b
        if random.randint(0, 1) == 0:
            column.append("#")     #把数据添加到数组b，往后添加
        else:
            column.append("*")
    nextCells.append(column)     #把数组b添加进数组a，如[（#，*，#）]
while True:
    print("\n")
    currentCells = copy.deepcopy(nextCells)   #复制数组a，因为数组a里面还有很多数组b，所以用copy.deepcopy
    for y in range(HEIGHT):       #这个循环是把每一个数组b，打印出来，一个数组b为一列（后附图1）
        for x in range(WIDTH):
            print(currentCells[x][y], end=" ")  # Print the # or space.
        print(1)
    for x in range(WIDTH):                  #这个是判断点位循环
        for y in range(HEIGHT):
            leftCoord = (x - 1) % WIDTH      #取模，具体取模是如何运算的看这个：https://blog.youkuaiyun.com/qq_41051690/article/details/100026508，
            rightCoord = (x + 1) % WIDTH
            aboveCoord = (y - 1) % HEIGHT
            belowCoord = (y + 1) % HEIGHT
            numNeighbors = 0
            if currentCells[leftCoord][aboveCoord] == "#":       #看图2
                numNeighbors += 1  # Top-left neighbor is alive.
            if currentCells[x][aboveCoord] == "#":
                numNeighbors += 1  # Top neighbor is alive.
            if currentCells[rightCoord][aboveCoord] == "#":
                numNeighbors += 1  # Top-right neighbor is alive.
            if currentCells[leftCoord][y] == "#":
                numNeighbors += 1  # Left neighbor is alive.
            if currentCells[rightCoord][y] == "#":
                numNeighbors += 1  # Right neighbor is alive.
            if currentCells[leftCoord][belowCoord] == "#":
                numNeighbors += 1  # Bottom-left neighbor is alive.
            if currentCells[x][belowCoord] == "#":
                numNeighbors += 1  # Bottom neighbor is alive.
            if currentCells[rightCoord][belowCoord] == "#":
                numNeighbors += 1  # Bottom-right neighbor is alive.
            if currentCells[x][y] == "#" and (numNeighbors == 2 or numNeighbors == 3):
                nextCells[x][y] = "#"
            elif currentCells[x][y] == "*" and numNeighbors == 3:
                nextCells[x][y] = "#"
            else:
                nextCells[x][y] = "*"
    time.sleep(60)  # Add a 1-second pause to reduce flickering.  #间隔多久循环一个
