这个python的小案例是五子棋游戏的实现，在这个案例中，我们可以实现五子棋游戏的两个玩家在指定的位置落子，画出落子后的棋盘，并且根据函数判断出输赢的功能。

这个案例的思路如下所示：

首先，根据棋盘的样子画出棋盘
然后，对棋盘进行初始化，将可以落子的位置进行统一化处理
接下来，就是进入游戏的环节，双方轮流落子，落子后，并将棋盘画出
最后，根据落子的位置判断选手的的输赢情况，游戏结束

五子棋游戏的设计和实现

代码如下：

def main(): print("五子棋游戏".center(50,'=')) guige=int(input("请输入棋盘的规格：")) #按照五子棋的棋盘样式，画出棋盘 print_init(guige) # 初始化棋盘 wzq = {} for i in range(1, guige + 1): for j in range(1, guige + 1): wzq[(i, j)] = "+" #重画棋盘 reprint(guige,wzq) #按照五子棋的棋盘样式，画出棋盘def print_init(guige): #打印出首行的棋盘列 for i in range(guige): print("%4d"%(i+1),end='') print() #双重循环，第一重为棋盘的行，隔一行输出棋盘的行数 for i in range(guige*2-1): #打印出类似 “1 +---+---+---+---+---+”，行号，+，— if(i%2==0): print("%-3d"%((i+2)/2),end='') #第二重循环，为棋盘的列，主要在于找出对应位置显示的内容 for j in range(guige * 4 - 3): if (j % 4 == 0): print("+", end='') else: print("-", end='') #打印出类似“ | | | | | |” else: print("%3s"%' ',end='') for j in range(guige*4-3): if(j%4==0): print("|",end='') else: print(" ",end='') #每行输出完成之后换行 print() #重画棋盘，对双方下子进行重画def reprint(guige,wzq): for i in range(guige*guige) : if i % 2 == 0: xuanshou = "X" else: xuanshou = "O" # 双方轮流下棋 while 1: print("现在轮到%s方落子" % xuanshou) position = input("请输入落子位置：") x_position = int(position.split()[0]) y_position = int(position.split()[1]) #判断输入的位置是否有子，有子一直输入，直到输入的位置无子 if wzq[(x_position, y_position)] in ["X", "O"]: print("您输入的位置有子，请重新输入！") else: break if wzq[(x_position, y_position)]=="+": #重画棋盘 wzq[(x_position, y_position)] = xuanshou for i in range(guige): print("%4d"%(i+1),end='') print() for i in range(guige*2-1): if(i%2==0): print("%-3d"%((i+2)/2),end='') for j in range(guige * 4 - 3): if (j % 4 == 0): x=(i+2)/2 y=j/4+1 print(wzq[(x,y)],end='') else: print("-", end='') else: print("%3s"%' ',end='') for j in range(guige*4-3): if(j%4==0): print("|",end='') else: print(" ",end='') print() else: isture=True print("您输入的位置已经有子，请重新输入！") # 判断输赢 # 第一种情况 wzq_win1(wzq,guige,xuanshou) # 第二种情况 wzq_win2(wzq,guige,xuanshou) # 第三种情况 wzq_win3(wzq,guige,xuanshou) # 第四种情况 wzq_win4(wzq,guige,xuanshou) else: print("游戏结束，平局！") # 判断输赢def wzq_win1(wzq,guige,xuanshou): # 第一种输赢情况 for i in range(1, guige + 1): for j in range(1, guige - 3): if (wzq[(i, j)] == wzq[(i, j + 1)] == wzq[(i, j + 2)] == wzq[(i, j + 3)] == wzq[(i, j + 4)] and wzq[(i, j)] in ["X", "O"]): print("%s获胜,游戏结束！" % xuanshou) exit()def wzq_win2(wzq,guige,xuanshou): # 第二种输赢情况 for i in range(1, guige - 3): for j in range(1, guige + 1): if (wzq[(i, j)] == wzq[(i + 1, j)] == wzq[(i + 2, j)] == wzq[(i + 3, j)] == wzq[(i + 4, j)] and wzq[(i, j)] in ["X", "O"]): print("%s获胜,游戏结束！" % xuanshou) exit()def wzq_win3(wzq,guige,xuanshou): # 第三种输赢情况 for i in range(1, guige - 3): for j in range(1, guige - 3): if (wzq[(i, j)] == wzq[(i + 1, j + 1)] == wzq[(i + 2, j + 2)] == wzq[(i + 3, j + 3)] == wzq[(i + 4, j + 4)] and wzq[(i, j)] in ["X", "O"]): print("%s获胜,游戏结束！" % xuanshou) exit()def wzq_win4(wzq, guige, xuanshou): # 第四种输赢情况 for i in range(1, guige - 3): for j in range(5, guige + 1): if (wzq[(i, j)] == wzq[(i +1, j - 1)] == wzq[(i + 2, j - 2)] == wzq[(i + 3, j - 3)] == wzq[(i + 4, j - 4)] and wzq[(i, j)] in ["X", "O"]): print("%s获胜,游戏结束！" % xuanshou) exit()main()

结果如下：
