if (count_black && count_white) { continue; }什么意思

这段代码是一个条件语句,其中 `count_black` 和 `count_white` 都是变量,判断它们的值是否都为真(非零)。如果两个变量的值都为真,则 `continue` 语句会跳过当前循环的本次迭代,然后继续执行下一次迭代。如果有一个或两个变量的值为假(0),则不会执行 `continue` 语句,继续执行当前循环的本次迭代。这段代码的意思可能是在对黑白棋子进行计数时,如果其中一个计数为0,则跳过这次迭代,因为没有需要处理的棋子。

green = yellow = blue = black = white = 0 try: # 有转换失败的可能,原因来自于上面矫正矩形出错 card_img_hsv = cv2.cvtColor(card_img, cv2.COLOR_BGR2HSV)#输入图像从一个色彩空间转换到另一个色彩空间 except: card_img_hsv = None if card_img_hsv is None: continue row_num, col_num = card_img_hsv.shape[:2] card_img_count = row_num * col_num
这是一段Python代码,其中将变量green、yellow、blue、black、white都赋值为0。接下来使用了try语句,可能是为了捕获异常或者处理错误。但是代码缺少完整性,无法确定具体的作用。
编写五子棋的完整python代码_python实现五子棋程序
以下是一个简单的五子棋 Python 代码,实现了基本的游戏功能:
```python
import numpy as np
# 定义棋盘大小
BOARD_SIZE = 15
# 定义棋子类型
EMPTY = 0
BLACK = 1
WHITE = 2
# 初始化棋盘
board = np.zeros((BOARD_SIZE, BOARD_SIZE), dtype=int)
# 定义函数,判断是否有五子连珠
def check_win(player):
for i in range(BOARD_SIZE):
for j in range(BOARD_SIZE):
if board[i][j] == player:
# 判断横向是否有五子连珠
if j+4 < BOARD_SIZE and board[i][j+1] == player and board[i][j+2] == player and board[i][j+3] == player and board[i][j+4] == player:
return True
# 判断纵向是否有五子连珠
if i+4 < BOARD_SIZE and board[i+1][j] == player and board[i+2][j] == player and board[i+3][j] == player and board[i+4][j] == player:
return True
# 判断右上到左下是否有五子连珠
if i+4 < BOARD_SIZE and j-4 >= 0 and board[i+1][j-1] == player and board[i+2][j-2] == player and board[i+3][j-3] == player and board[i+4][j-4] == player:
return True
# 判断左上到右下是否有五子连珠
if i+4 < BOARD_SIZE and j+4 < BOARD_SIZE and board[i+1][j+1] == player and board[i+2][j+2] == player and board[i+3][j+3] == player and board[i+4][j+4] == player:
return True
return False
# 定义函数,判断是否平局
def check_draw():
return np.count_nonzero(board == EMPTY) == 0
# 定义函数,打印棋盘
def print_board():
print(" ", end=" ")
for i in range(BOARD_SIZE):
print(i+1, end=" ")
print()
for i in range(BOARD_SIZE):
print(i+1, end=" ")
for j in range(BOARD_SIZE):
if board[i][j] == EMPTY:
print(".", end=" ")
elif board[i][j] == BLACK:
print("X", end=" ")
else:
print("O", end=" ")
print()
# 定义函数,执行游戏
def play():
player = BLACK
while True:
print_board()
if player == BLACK:
print("黑方落子:")
else:
print("白方落子:")
x = int(input("请输入横坐标:")) - 1
y = int(input("请输入纵坐标:")) - 1
if board[x][y] != EMPTY:
print("此处已有棋子,请重新输入!")
continue
board[x][y] = player
if check_win(player):
print_board()
if player == BLACK:
print("黑方胜利!")
else:
print("白方胜利!")
break
if check_draw():
print_board()
print("平局!")
break
player = WHITE if player == BLACK else BLACK
# 开始游戏
play()
```
在代码中,我们使用了 NumPy 数组来表示棋盘,使用 0 表示空位,1 表示黑子,2 表示白子。使用 `check_win()` 函数来判断是否有五子连珠,使用 `check_draw()` 函数来判断是否平局。在 `play()` 函数中,使用 `input()` 函数来获取玩家输入的坐标,落子后判断游戏是否结束。如果游戏结束,打印胜者并退出游戏,否则交换玩家并继续游戏。
