ATBS Python康威生命游戏代码运行仅显示空格问题排查

核心问题是缩进错误，这是抄写Python代码时最高发的问题：Python不使用大括号区分代码块，完全靠缩进层级判断代码归属，你的代码里while True主循环的循环体只包含2行代码：

• 打印5个换行分隔步
• 深拷贝上一步的细胞状态到currentCells

原本应该放在循环内部的「打印当前细胞网格」「计算下一代细胞状态」「1秒暂停防闪烁」逻辑全部顶格写在了循环外部，属于永远不会被执行的死代码。程序启动后会陷入无限空转，持续输出空行，你看到的“仅显示空格”实际是不断刷屏的空白行，活细胞渲染、演化逻辑完全没有运行。

只需要把从# Print currentCells on the screen:开始，到time.sleep(1)结束的所有代码，统一缩进4个空格，放到while True的循环体内部即可，其他逻辑无需修改：

# Conway's Game of Life
import random, time, copy
WIDTH = 60
HEIGHT = 20

# Create a list of list for the cells:
nextCells = []
for x in range(WIDTH):
    column = []  # Create a new column
    for y in range(HEIGHT):
        if random.randint(0, 1) == 0:
            column.append('#')  # add a living cell
        else:
            column.append(' ')  # add a dead cell
    nextCells.append(column)  # NextCells is a list of a column lists.
    
while True:  # Main program loop
    print('\n\n\n\n\n')  # Seperate each step with newlines
    currentCells = copy.deepcopy(nextCells)

    # Print currentCells on the screen:
    for y in range(HEIGHT):
        for x in range(WIDTH):
            print(currentCells[x][y], end='')  # Print the # or space
        print()  # Print a newline at the end of the row

    # Calculate the next step's cells based on current steps cells:
    for x in range(WIDTH):
        for y in range(HEIGHT):
            # Get neighboring coordinates:
            # '% WIDTH' ensures leftCoord is always between 0 and WIDTH -1
            leftCoord = (x - 1) % WIDTH
            rightCoord = (x + 1) % WIDTH
            aboveCoord = (y - 1) % HEIGHT
            belowCoord = (y + 1) % HEIGHT
            
            # Count number of living neighbors
            numNeighbors = 0
            if currentCells[leftCoord][aboveCoord] == '#':
                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  # below-left is alive
            if currentCells[x][belowCoord] == '#':
                numNeighbors += 1  # below is alive
            if currentCells[rightCoord][belowCoord] == '#':
                numNeighbors += 1  # below-right is alive
            
            # Set cell based on Conway's Game of Life rules:
            if currentCells[x][y] == '#' and (numNeighbors == 2 or numNeighbors == 3):
                # Living cells with 2 or 3 neighbors stay alive:
                nextCells[x][y] = '#'
            elif currentCells[x][y] == ' ' and numNeighbors == 3:
                # Dead cells with 3 neighbors become alive:
                nextCells[x][y] = '#'
            else:
                # Everything else dies or stays dead
                nextCells[x][y] = ' '

    time.sleep(1)  # add a 1 second pause to reduce flickering
