我正在做一个Python项目，其目标是让一支部队（士兵，升级士兵和坦克）相互攻击。
我为长代码道歉，但是当我快要结束时遇到了问题，希望你能理解：＆gt;
该项目的目标是使用类继承和许多其他东西。 我的档案：
PointLine.py：

class Point(object):
#includes coordiantes - x and y
def __init__(self, X, Y):
self._X = X
self._Y = Y
def __repr__(self):

class Line(Point):
#consists of two points
def __init__(self, point1,point2):
if point1 != None and point2 != None:
self._point1 = point1
self._point2 = point2
else:
myLine = None
def __repr__(self):
return "X1 = " + str(point1._X) + " X2 = " + str(point2._X) + " Y1 = " + str(point1._Y) + " Y2 = " + str(point2._Y)
def arentPointsEqual(self, point1, point2):
if point1._X != point2._X and point1._Y != point2._Y:
myLine = Line(point1, point2)
else:
print "ERROR ! Two points are equal"
return False
def returnLength(self):
Xs = math.pow((self._point2._X - self._point1._X), 2)
Ys = math.pow((self._point2._Y - self._point1._Y), 2)
beforeSqrt = Xs + Ys
return math.sqrt(beforeSqrt)

问题是：当我尝试在棋盘上放置一些部队时（无论哪一个都没关系）它只是将它放到给定X中的整个列表中。
例如：
输入x = 1时，y = 1：
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
[0, First's Player soldier, 0, 0, 0, 0, 0, 0, 0, 0]
请帮我解决此问题。

答案 0 :(得分：1)
由于您在设置电路板时使用了可变对象（列表）的方式，这是一个错误。您的电路板的每一行实际上都是对同一个列表的引用，因此您看到的行为。取代
board = [[0] * 10] * 10
与
board = [[0 for _ in range(10)] for _ in range(10)]
