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：")

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)]=="+":

# 判断输赢
# 第一种情况

# 第三种情况
wzq_win3(wzq,guige,xuanshou)
# 第四种情况

else:

# 判断输赢

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):

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"]):
