生命游戏python代码

以下是一个简单的生命游戏Python代码：

import random
import copy

# 游戏界面大小
WIDTH = 20
HEIGHT = 20

# 初始化游戏界面
board = []
for y in range(HEIGHT):
  row = []
  for x in range(WIDTH):
    if random.random() > 0.5:
      row.append('*')
    else:
      row.append('.')
  board.append(row)

# 打印游戏界面
def print_board(board):
  for row in board:
    print(' '.join(row))

# 计算周围细胞数量
def count_neighbors(board, x, y):
  neighbors = 0
  for dx in range(-1, 2):
    for dy in range(-1, 2):
      if dx == 0 and dy == 0:
        continue
      if x+dx < 0 or x+dx >= WIDTH or y+dy < 0 or y+dy >= HEIGHT:
        continue
      if board[y+dy][x+dx] == '*':
        neighbors += 1
  return neighbors

# 进行一轮游戏
def step(board):
  new_board = copy.deepcopy(board)
  for y in range(HEIGHT):
    for x in range(WIDTH):
      neighbors = count_neighbors(board, x, y)
      if board[y][x] == '*' and (neighbors < 2 or neighbors > 3):
        new_board[y][x] = '.'
      elif board[y][x] == '.' and neighbors == 3:
        new_board[y][x] = '*'
  return new_board

# 主循环
while True:
  print_board(board)
  input('Press Enter to continue...')
  board = step(board)

这个代码实现了基本的生命游戏，首先随机生成一个游戏界面，然后每轮根据每个细胞周围的细胞数量来判断该细胞的状态，最后更新游戏界面。每次更新后，界面会打印出来，并等待用户按下回车键继续下一轮。
