这是我第一次在这里发帖，而且我是Python新手，所以如果我出错了，请耐心等待！我已经看到了类似的问题，但看不出明确的解决方案。这必须有一个简单的解决方案，但它让我整天感到沮丧。
我正在尝试在构造函数中创建类“Slot”的多个对象 班级“董事会”。在制作每个对象之后，我将它附加到列表中。 最后，我将遍历列表中的每个对象并调用'getHandles'方法，这应该是 输出他们独特的结果。而是显示最后一个插槽对象的结果。
Board类构造函数：
class Board:
slots = []
def __init__(self):
slot1 = Slot(1); self.slots.append(slot1);
slot2 = Slot(2); self.slots.append(slot2);
slot3 = Slot(3); self.slots.append(slot3);
slot4 = Slot(4); self.slots.append(slot4);
slot5 = Slot(5); self.slots.append(slot5);
slot6 = Slot(6); self.slots.append(slot6);
slot7 = Slot(7); self.slots.append(slot7);
slot8 = Slot(8); self.slots.append(slot8);
slot9 = Slot(9); self.slots.append(slot9);
print("\nprinting slot objects in list 'slot'\n");
counter = 0;
while counter < len(self.slots):
print("slot number :"+str(self.slots[counter].getPosition()));
print("slot value :"+str(self.slots[counter].getHandles()));
counter +=1;
插槽类构造函数：
#Slot class constructor
def __init__(self,n):
self.setPosition(n);
positions = coords.getLargeGridPosition(n);
self.U[2] = positions[1]; self.D[2] = positions[2];
self.L[2] = positions[3]; self.R[2] = positions[4];
print("made slot object : "+str(self.getPosition()));
print("handle values: ");
self.getHandles();
print(" - ");
def getHandles(self):
print(" U:"+str(self.U)+" D:"+str(self.D)+" L:"+str(self.L)+" R:"+str(self.R));
这是我制作'Board'对象时得到的结果：
第一部分输出（在Board构造函数中创建插槽和附加）：
>>> b = Board()
made slot object : 1
handle values:
U:[1, 2, 2] D:[2, 1, 20] L:[3, 4, 10] R:[4, 3, 12]
-
made slot object : 2
handle values:
U:[1, 2, 5] D:[2, 1, 23] L:[3, 4, 13] R:[4, 3, 15]
-
made slot object : 3
handle values:
U:[1, 2, 8] D:[2, 1, 26] L:[3, 4, 16] R:[4, 3, 18]
-
made slot object : 4
handle values:
U:[1, 2, 29] D:[2, 1, 47] L:[3, 4, 37] R:[4, 3, 39]
-
等等。 第二部分输出（为列表中的每个对象调用getHandle方法）：
printing slot objects in list 'slot'
slot number :1
U:[1, 2, 62] D:[2, 1, 80] L:[3, 4, 70] R:[4, 3, 72]
slot value :None
slot number :2
U:[1, 2, 62] D:[2, 1, 80] L:[3, 4, 70] R:[4, 3, 72]
slot value :None
slot number :3
U:[1, 2, 62] D:[2, 1, 80] L:[3, 4, 70] R:[4, 3, 72]
slot value :None
slot number :4
U:[1, 2, 62] D:[2, 1, 80] L:[3, 4, 70] R:[4, 3, 72]
slot value :None
slot number :5
U:[1, 2, 62] D:[2, 1, 80] L:[3, 4, 70] R:[4, 3, 72]
等等。如何使变量slot1 / slot2 是指个别物品？
我已经尝试将board对象传递给slot构造函数，并使slot构造函数将'self'传递回Board对象。仍然为所有人输出单个对象的结果。 我很感激任何帮助。谢谢。

答案 0 :(得分：0)
正如Pavel在评论中所说，在类级别定义的任何东西都是一个类变量，在所有实例之间共享。您需要在__init__中定义这些变量，方法是将它们分配给self：
class Slot: #slot class<------------------------------------------------
def __init__(self,n):
self.U = [1,2,"gridPosition"] #1 up
self.D = [2,1,"gridPosition"] #2 down
self.L = [3,4,"gridPosition"] #3 left
self.R = [4,3,"gridPosition"] #4 right
self.handles = [U,D,L,R] #handles 0/1/2/3
self.tileValue = 0; #value 0 - 8
self.tilePosition = 0; #slot 1 - 9
self.overallStrain = 0; # |0-->+
你也应该知道，这里有很多极其单一的Python例子。例如，整个Board init应该只是：
def __init__(self):
self.slots = [Slot(i+1) for i in range(10)]
print("\nprinting slot objects in list 'slot'\n");
for slot in self.slots:
print("slot number :%s" % slot.getPosition());
print("slot value :%d" slot.getHandles());
此外，除非有一个很好的理由，否则我们不鼓励定义getter和setter，因为你只是访问变量，所以你不会在这里。您应该分配并返回self.position等等。
