我有一个正确运行的连接四程序，但我想将我的 match_in_direction() 方法打印到屏幕上...我的代码如下
class ConnectFour(object):
这将初始化板：
def __init__(self):
self.board = [[None for i in range(7)] for j in range(8)]
这得到每个播放点的位置：
def get_position(self, row, column):
assert row >= 0 and row < 6 and column >= 0 and column < 7
return self.board[row][column]
这应该检查所玩的筹码是否匹配：
def match_in_direction(self, row, column, step_row, step_col):
assert row >= 0 and row < 6 and column >= 0 and column < 7
assert step_row != 0 or step_col != 0 # (0,0) gives an infinite loop
match = 1
while True:
nrow = row + step_row
ncolumn = column + step_col
if nrow >=0 and nrow <6 and ncolumn >=0 and ncolumn <7:
if self.board[row][column] == self.board[nrow][ncolumn]:
match == match+1
row = nrow
column = ncolumn
else:
return match
else:
return match
print match
这将是一个基于用户输入的游戏
def play_turn(self, player, column):
""" Updates the board so that player plays in the given column.
player: either 1 or 2
column: an integer between 0 and 6
"""
assert player == 1 or player == 2
assert column >= 0 and column < 7
for row in xrange(6):
if self.board[row][column] == None:
self.board[row][column] = player
return
打印板：
def print_board(self):
print "-" * 29
print "| 0 | 1 | 2 | 3 | 4 | 5 | 6 |"
print "-" * 29
for row in range(5,-1,-1):
s = "|"
for col in range(7):
p = self.get_position(row, col)
if p == None:
s += " |"
elif p == 1:
s += " x |"
elif p == 2:
s += " o |"
else:
# This is impossible if the code is correct, should never occur.
s += " ! |"
print s
print "-" * 29
而我的用法：
b = ConnectFour()
b.play_turn(1, 3)
b.play_turn(1, 3)
b.play_turn(1, 4)
b.match_in_direction(0,3,0,2)
b.print_board()
我当前的输出给了我很好的位置......但是它没有打印应该是 2 的 match_in_direction(0,3,0,2) 因为那是匹配的筹码数量......任何帮助都会很大赞赏。
