写一个打地鼠代码

好的，以下是一个简单的打地鼠游戏的代码示例：

import random

# 游戏配置
ROWS = 3
COLS = 3
HOLE_SYMBOL = 'O'
MOLE_SYMBOL = 'M'
BLANK_SYMBOL = '-'
NUM_MOLES = 3
TIME_LIMIT = 30

# 初始化游戏板
board = [[HOLE_SYMBOL for j in range(COLS)] for i in range(ROWS)]

# 创建地鼠
moles = []
for i in range(NUM_MOLES):
    row = random.randint(0, ROWS-1)
    col = random.randint(0, COLS-1)
    while board[row][col] == MOLE_SYMBOL:
        row = random.randint(0, ROWS-1)
        col = random.randint(0, COLS-1)
    board[row][col] = MOLE_SYMBOL
    moles.append((row, col))

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

# 游戏循环
hits = 0
misses = 0
time_left = TIME_LIMIT
while time_left > 0:
    print_board(board)
    print('Time left:', time_left)
    print('Hits:', hits)
    print('Misses:', misses)
    row = int(input('Row: '))
    col = int(input('Col: '))
    if row < 0 or row >= ROWS or col < 0 or col >= COLS:
        print('Invalid input!')
        continue
    if board[row][col] == MOLE_SYMBOL:
        board[row][col] = BLANK_SYMBOL
        hits += 1
        print('Hit!')
    else:
        misses += 1
        print('Miss!')
    time_left -= 1

# 游戏结束
print('Time is up!')
print('Hits:', hits)
print('Misses:', misses)
print('Score:', hits - misses)

该代码使用二维列表表示游戏板，随机创建若干个地鼠，然后在游戏循环中允许玩家输入行和列，判断玩家是否击中地鼠。最后计算得分并输出。
