用于存储3个值的ArrayList 3维列表(错误:字典中不存在给定键。)

# 创建一个3维列表
arrayList3D = []
for i in range(3):
    arrayList2D = []
    for j in range(3):
        arrayList1D = []
        for k in range(3):
            arrayList1D.append(None)  # 初始化每个值为None
        arrayList2D.append(arrayList1D)
    arrayList3D.append(arrayList2D)

# 设置值
arrayList3D[0][0][0] = value1
arrayList3D[1][1][1] = value2
arrayList3D[2][2][2] = value3

# 获取值
value = arrayList3D[0][0][0]

# 修改值
arrayList3D[0][0][0] = newValue

# 删除值
del arrayList3D[0][0][0]

# 添加值
arrayList3D[0][0].append(newValue)

# 获取列表长度
length = len(arrayList3D[0][0])

# 遍历列表
for i in range(len(arrayList3D)):
    for j in range(len(arrayList3D[i])):
        for k in range(len(arrayList3D[i][j])):
            value = arrayList3D[i][j][k]
            # 进行操作
