在这个教程中,我将展示如何利用Python来做一个井字游戏。这将包括函数、列表、if语句、while循环、for循环以及错误处理等等。
首先,我们将创建两个函数,第一个函数将会打印出井字游戏的背景模板:
def print_board():
for i in range(0,3):
for j in range(0,3):
print map[2-i][j],
if j != 2:
print "|",
def print_board():&&&&for i in range(0,3):&&&&&&&&for j in range(0,3):&&&&&&&&&&&&print map[2-i][j],&&&&&&&&&&&&if j != 2:&&&&&&&&&&&&&&&&print "|",&&&&&&&&print ""
在这里,我们使用了两个for循环,要遍历一个名为map的列表变量。这个变量是一个二维列表,将保存每个位置的信息。
由于我会按照小键盘的数字来进行对照位置(稍后你会看到),所以第一个值我们把它设为(2-i),然后我们想用"|"来进行分割我们的位置,所以在每个位置打印完之后,我们给他打印一个"|",我们在这里print map[2-i][j],使用了逗号,以保证他们在同一行被打印出来。
现在,这个函数可以打印一个游戏的背景啦,它看起来是这个样子滴:
&&|&& |&& &&|&& |&& &&|&& |
X | X |&& O | X | O &&| O | X
X | X | X X | X | X X | X | X
接下来,我们创建一个check_done()函数,它会在每轮结束之后检查游戏是否结束了,如果游戏结束,那么返回True并打印一条消息。
def check_done():
for i in range(0,3):
if map[i][0] == map[i][1] == map[i][2] != " " \
or map[0][i] == map[1][i] == map[2][i] != " ":
print turn, "won!!!"
return True
if map[0][0] == map[1][1] == map[2][2] != " " \
or map[0][2] == map[1][1] == map[2][0] != " ":
print turn, "won!!!"
return True
if " " not in map[0] and " " not in map[1] and " " not in map[2]:
print "Draw"
return True
return False

def check_done():&&&&for i in range(0,3):&&&&&&&&if map[i][0] == map[i][1] == map[i][2] != " " \&&&&&&&&or map[0][i] == map[1][i] == map[2][i] != " ":&&&&&&&&&&&&print turn, "won!!!"&&&&&&&&&&&&return True&&&&&if map[0][0] == map[1][1] == map[2][2] != " " \&&&&or map[0][2] == map[1][1] == map[2][0] != " ":&&&&&&&&print turn, "won!!!"&&&&&&&&return True&&&&&if " " not in map[0] and " " not in map[1] and " " not in map[2]:&&&&&&&&print "Draw"&&&&&&&&return True&&&&&return False
首先,我们会检查水平和垂直方向,是不是有三格是相同、并且不为空(所以他不会认为连续三个空行是符合条件的),其次,我们以相同的方式来检查对角线。
这8行如果有一行符合条件,那么游戏结束并且打印出“Won!!!”并返回True,同时注意turn这个变量,它的作用是判断现在下棋的是那一方,最终展现出来的消息将会是“X赢了!!”或“O赢了!!”。
接下来这个函数会判断假如没有一个位置是空的,那么就意味着没有人能够赢得比赛(前面判断过了),那么就打印出平局,并且返回True。
如果没有上述两种情况,那么游戏还没结束,返回False。
OK,现在我们有了两个函数,接下来开始我们真正的程序,首先来创建三个变量:
turn = "X"
map = [[" "," "," "],
[" "," "," "],
[" "," "," "]]
done = False
turn = "X"map = [[" "," "," "],&&&&&& [" "," "," "],&&&&&& [" "," "," "]]done = False
我已经告诉过你这三个变量是熟么意思了,假如你忘了的话,那么看看下面:
turn:该谁走了
map:游戏的背景地图
done:这个游戏到底有木有结束
接下来,这样写:
while done != True:
print_board()
print turn, "'s turn"
moved = False
while moved != True:
while done != True:&&&&print_board()&&&&&print turn, "'s turn"&&&&print&&&&&moved = False&&&&while moved != True:
里面有一个while循环,直到done为True为止,我们打印出该轮到谁走了。
然后创建一个名为moved的变量,检查玩家是不是移动了,如果没有移动,则进入下一个循环。
接下来,我们打印玩家该怎样去下:
print "Please select position by typing in a number between 1 and 9, see below for which number that is which position..."
print "7|8|9"
print "4|5|6"
print "1|2|3"
print "Please select position by typing in a number between 1 and 9, see below for which number that is which position..."print "7|8|9"print "4|5|6"print "1|2|3"print
pos = input("Select: ")
if pos &=9 and pos &=1:
try:&&&&pos = input("Select: ")&&&&if pos &=9 and pos &=1:
我们希望玩家输入一个数字,然后我们检查是不是在1~9之间,同时,我们还得增加一个错误处理,比如玩家输入”Hello”,程序不能就这么退出了。
现在,我们需要检查他走的这一步能不能走:
if X != 0:
Y = pos/3X = pos%3if X != 0:&&&&X -=1else:&&&&X = 2&&&&Y -=1
hah,睁大眼睛啦,首先我们得到一个X和Y的值,然后使用他们来检查,他要下的那个位置是不是空的,接下来我会向你解释X和Y他们是肿么工作的:
位置1:Y = 1/3 = 0, X = 1%3 = 1; x -= 1 = 0
位置2:Y = 2/3 = 0, X = 2%3 = 2; X -= 1 = 1
位置3:Y = 3/3 = 1, X = 3%3 = 0; X = 2, Y -= 1 = 0
下面的自己算啊,我直接上结论(靠,Hexo默认的模板不显示表格啊,我在mou上面编辑的时候比下面的漂亮多了!):
aha,这个位置和我们键入的是一样的!
print "7|8|9"
print "4|5|6"
print "1|2|3"
print "7|8|9"print "4|5|6"print "1|2|3"
现在我们完成大部分工作了,但是还有几行代码:
map[Y][X] = turn
moved = True
done = check_done()
if done == False:
if turn == "X":
turn = "O"
turn = "X"
print "You need to add a numeric value"
123456789101112
map[Y][X] = turnmoved = Truedone = check_done()&if done == False:&&&&if turn == "X":&&&&&&&&turn = "O"&&&&else:&&&&&&&&turn = "X"&except:&&&&print "You need to add a numeric value"
嗯,我们给moved变量复制为True,并检查是否结束了,木有结束的话变换角色换下一个人走。
OK,差不多结束了,假如你只是想Ctrl+C 和 Ctrl+V的话,下面是全部的代码,希望你学到了点什么,( ^_^ )/~~拜拜。
def print_board():
for i in range(0,3):
for j in range(0,3):
print map[2-i][j],
if j != 2:
print "|",
def check_done():

if map[i][0] == map[i][1] == map[i][2] != " " \
or map[0][i] == map[1][i] == map[2][i] != " ":
print turn, "won!!!"
return True
if map[0][0] == map[1][1] == map[2][2] != " " \
or map[0][2] == map[1][1] == map[2][0] != " ":
print turn, "won!!!"
return True
if " " not in map[0] and " " not in map[1] and " " not in map[2]:
print "Draw"
return True
return False
turn = "X"
map = [[" "," "," "],
[" "," "," "],
[" "," "," "]]
done = False
while done != True:
print_board()
print turn, "'s turn"
moved = False
while moved != True:
print "Please select position by typing in a number between 1 and 9, see below for which number that is which position..."
print "7|8|9"
print "4|5|6"
print "1|2|3"
pos = input("Select: ")
if pos &=9 and pos &=1:
if X != 0:
if map[Y][X] == " ":
map[Y][X] = turn
moved = True
done = check_done()
if done == False:
if turn == "X":
turn = "O"
turn = "X"
