Question

我在这样的方法中有一个循环：

from random import randint

class Player:
    def __init__(self, position=0):
        self.position = position

    def move(self, move):
        self.position += move

class Game:
    def __init__(self, size=10, p1=1, p2=1):
        self.size = size
        self.p1 = Player()
        self.p2 = Player()

    def finished(self):
        if self.p1.position >= self.size:
            return True
        if self.p2.position >= self.size:
            return True

    def run(self):
        while True:
            roll = randint(1,2)

            self.p2.move(roll)
            if self.finished():
                break

            roll = randint(1,2)

            self.p1.move(roll)
            if self.finished():
                break

        if self.p2.position >= self.p1.position: # if player 2 won return 2, else 1
            return 2
        else:
            return 1

    def jump(self, iterations):
        move1, move2, i = 0,0,0
        while i < iterations:
            print(move1, move2) # move1 is 0 again

            a = Game(self.size, self.p1.position+1, self.p2.position)
            x = a.run()
            print(x) # x is either 1 or 2, for the sake of testing 
                     # it's been set to always 1
            if x == 1:
                move1 += 1
            print(move1) # if move1 is incremented, it is shown here successfully    

            b = Game(self.size, self.p1.position+2, self.p2.position)
            y = b.run()

            if y == 1:
                move2 += 1

            i += 1

        if move2 >= move1:
            return 2
        else:
            return 1

human, comp, i = 0, 0, 0
times = 10
while i < times:
    g = Game()
    while True:
        roll = g.jump(4)
        g.p1.move(roll)
        if g.finished():
            human += 1
            break

        roll = g.jump(4)
        g.p2.move(roll)
        if g.finished():
            comp += 1
            break
    i += 1

但是，在每个循环开始时，应该更新应该更新的变量。我的缩进似乎是正确的，所以我不确定问题是什么。它可以是变量范围吗？

感谢您的帮助。

编辑：这是所有代码的粘贴：http://pastebin.com/GjKA8yag

编辑：在帖子中添加了所有代码。以下是底部控制器代码应该发生的事情：

初始化游戏，g。 g有2个玩家，每个玩家都有一个位置，他们需要到达棋盘的最后才能获胜，棋盘长10平方，他们可以一次移动1或2个方格。

要确定要移动的方格数，我们使用jump方法。 jump方法在其中创建了两个游戏，其中一个游戏初始化为player1，距离他前方1个方格，其中一个游戏初始化，其中玩家1前方2个方格。然后使用run方法随机完成这些游戏，返回一个值以查看谁赢得了该游戏（玩家2为2，玩家1为1。

这已经完成iterations次，然后是哪个游戏更成功，即最初向前移动1次或向前移动2次，这是将在实际游戏中采取的移动，g

打印声明的样本：

第一行是print(move1, move2)，它位于while循环的开头。然后print(x)作为run()方法返回的值，然后print(move1)增加后。{/ p>

我在Windows 8上运行Python 3.3 x64。

结果：切换到Python 2.7.3并且它现在正在工作。

Answer 1

    def jump(self, iterations):
        move1, move2, i = 0,0,0
        while i < iterations:
            print(move1, move2) # move1 is 0 again

            a = Game(self.size, self.p1.position+1, self.p2.position)
            x = a.run()
            print("who won game a? : " + str(x)) # x is either 1 or 2, for the sake of testing 
                     # it's been set to always 1
            if x == 1:
                move1 += 1
            print("move 1 is: " + str(move1)) # if move1 is incremented, it is shown here successfully    

            b = Game(self.size, self.p1.position+2, self.p2.position)
            y = b.run()
            print("who won game b? : " + str(y))

            if y == 1:
                move2 += 1
            print("move 2 is: " + str(move2))

            i += 1

        if move2 >= move1:
            return 2
        else:
            return 1

human, comp, i = 0, 0, 0
times = 10
while i < times:
    g = Game()
    print("new game")
    while True:
        print("position of 1 is:" + str(g.p1.position))
        print("position of 2 is:" + str(g.p2.position))
        roll = g.jump(4)
        print("first jump finished")
        g.p1.move(roll)
        if g.finished():
            human += 1
            break

        roll = g.jump(4)
        print("second jump finished")
        g.p2.move(roll)
        if g.finished():
            comp += 1
            break
    i += 1

以下是我更改的部分。我只在你的代码中添加了print语句这是输出请告诉我哪一部分输出对您没有意义。
