1. 游戏思路和流程图
实现功能,现实生活中的井字棋玩法
游戏流程图
2. 使用模块和游戏提示
import random
def game_info():
print('欢迎来到井字棋游戏')
print('输入数字1~9进行下棋')
3. 棋盘显示
def display_board(checkerboard):
'''棋盘显示'''
print(' '.join(checkerboard[6:9]))
print(' '.join(checkerboard[3:6]))
print(' '.join(checkerboard[:3]))
4. 用户下棋输入限制
def chess_limited(number,checkerboard):
'''用户落棋限制
:param number 用户输入
:param checkerboard 棋盘列表
:return 返回验证过的用户输入'''
while True:
if not number.isdigit():
print('请输入整数数字')
elif number not in '1 2 3 4 5 6 7 8 9'.split():
print('请输入1~9之间的数字')
elif checkerboard[int(number)-1]!='_':
print('棋盘上已经有棋子了')
else:
break
number = input()
return int(number)
5. 双选验证
def Double_choice(a,b,hint):
'''双选择验证函数
:param a 第一个选项值
:param b 第二个选项值
:param hint 选项信息
:return 返回输入值'''
choice=''
while choice.lower() !=a and choice.lower() !=b:
print(hint)
choice=input()
return choice
6. 获胜验证
def referee(choice,checkerboard):
'''判断谁胜利了还是平局'''
if checkerboard[0] == choice and checkerboard[1] == choice and checkerboard[2] == choice:
return True #123
if checkerboard[3] == choice and checkerboard[4] == choice and checkerboard[5] == choice:
return True #456
if checkerboard[6] == choice and checkerboard[7] == choice and checkerboard[8] == choice:
return True #789
if checkerboard[0] == choice and checkerboard[3] == choice and checkerboard[6] == choice:
return True #147
if checkerboard[1] == choice and checkerboard[4] == choice and checkerboard[7] == choice:
return True #258
if checkerboard[2] == choice and checkerboard[5] == choice and checkerboard[8] == choice:
return True #369
if checkerboard[2] == choice and checkerboard[4] == choice and checkerboard[6] == choice:
return True #357
if checkerboard[0] == choice and checkerboard[4] == choice and checkerboard[8] == choice:
return True #159
return False
6. 用户落子处理
def user_play(user_choice,checkerboard):
'''用户选择落子点
:param user_choice 用户所选棋子
:param checkerboard 棋盘列表
:param 返回用户落子完后的棋盘列表'''
print('请你选择落子点')
number=chess_limited(input(),checkerboard)
checkerboard[number-1]=user_choice
return checkerboard
7. 电脑落子处理
def compute_play(compute_choice,checkerboard):
'''电脑选择落子点(电脑ai)
:param compute_choice 电脑所选的棋子
:param checkerboard 棋盘
:return 电脑下过的棋盘'''
copy_win=compute_win(compute_choice,checkerboard)
if copy_win: #电脑获胜
checkerboard=copy_win
return checkerboard
user_win=prevent_user_win(compute_choice, checkerboard)
if user_win: #阻止用户获胜
checkerboard = user_win
return checkerboard
angle=choice_random(compute_choice,checkerboard,[0,2,6,8])
if angle: #角落点
checkerboard =angle
return checkerboard
center=choice_random(compute_choice,checkerboard,[4])
if center: #中心落点
checkerboard = center
return checkerboard
side = choice_random(compute_choice, checkerboard, [1, 3, 5, 7])
if side: #边落点
checkerboard =side
return checkerboard
return checkerboard
8. 电脑获胜
def compute_win(compute_choice,checkerboard):
'''获胜的方法(模拟算法)
:return 获胜的棋盘, False 没有可落子的地方'''
compute_choice=compute_choice.lower()
for i in range(9):
copy_board = checkerboard.copy()
if copy_board[i]=='_':
copy_board[i]=compute_choice
if referee(compute_choice,copy_board):
checkerboard[i] = compute_choice
return checkerboard
return False
9. 阻止玩家获胜
def prevent_user_win(compute_choice,checkerboard):
'''阻止玩家获胜(模拟玩家获胜下子)
:return 阻止用户获胜的棋盘 False 没有可以阻止的落子'''
user_choice = 'O' if compute_choice.lower() == 'x' else 'X'
user_choice=user_choice.lower()
for i in range(9):
copy_board = checkerboard.copy()
if copy_board[i] == '_':
copy_board[i] = user_choice
if referee(user_choice, copy_board):
#成功阻止玩家获胜....
checkerboard[i]=compute_choice
return checkerboard
return False
10. 电脑随机落点
def choice_random(compute_choice,checkerboard,choice_list):
'''随机下棋点'''
for i in choice_list:
if checkerboard[i]=='_':
checkerboard[i]=compute_choice
return checkerboard
return False
11. 游戏主程序
def game_start(user_choice,sequence_flag):
'''游戏核心处理
:param user_choice 用户所选棋子
:param sequence_flag 决定先后手'''
checkerboard=['_' for i in range(9)] #棋盘列表
compute_choice = 'O' if user_choice.lower()=='x' else 'X'
if sequence_flag: #显示棋盘
print('玩家先走')
else:
checkerboard=compute_play(compute_choice,checkerboard) #电脑先走棋盘
print('电脑先走')
while True:
display_board(checkerboard)
checkerboard = user_play(user_choice, checkerboard)
if referee(user_choice,checkerboard):
print('用户赢了...')
display_board(checkerboard)
break
checkerboard = compute_play(compute_choice, checkerboard)
if referee(compute_choice,checkerboard):
print('电脑赢了...')
display_board(checkerboard)
break
if '_' not in checkerboard:
print('平局...')
display_board(checkerboard)
break
12. 游戏外壳
def game_shell():
'''外壳程序'''
game_info() # 游戏开始提示
user_choice = Double_choice('x', 'o', hint='请选择你的棋子 X or O')
sequence_flag = random.randint(0, 1)
game_start(user_choice,sequence_flag)
while True:
message='你想在玩一次吗(Y or N)'
again_flag=Double_choice('y','n',message)
if again_flag=='n':
break
if sequence_flag:
sequence_flag=0
else:
sequence_flag=1
game_start(user_choice,sequence_flag)
13. 运行游戏
game_shell()
