Python 修改列表列表中的项目时,也会更改其他列表中相同项目的位置

Python 修改列表列表中的项目时,也会更改其他列表中相同项目的位置,python,list,Python,List,下面的代码是函数的一部分,但我遇到的问题是在这些行上 # Global variables NUM_MECS = 2 MAX_MEC_CAPACITY = 2 VNF_TYPES = 2 # Mec capacity to hold a vnf served_vnfs = list(range(MAX_MEC_CAPACITY+1)) # 0 does not count as capacity # All possible mec states as f

下面的代码是函数的一部分,但我遇到的问题是在这些行上

# Global variables
NUM_MECS          = 2
MAX_MEC_CAPACITY  = 2
VNF_TYPES         = 2

# Mec capacity to hold a vnf
served_vnfs = list(range(MAX_MEC_CAPACITY+1)) # 0 does not  count as capacity
# All possible mec states as far as holded vnfs
mec_capacity_states = [list(s) for s in itertools.product(served_vnfs, repeat=VNF_TYPES)]
# All possible states with defined number of mecs
mecs_states = [list(p) for p in itertools.product(mec_capacity_states, repeat=NUM_MECS)]
这将生成一个列表列表,如下所示:

out: [[[0, 0], [0, 0]], [[0, 0], [0, 1]], [[0, 0], [0, 2]], [[0, 0], [1, 0]], [[0, 0], [1, 1]], [[0, 0], [1, 2]], [[0, 0], [2, 0]], [[0, 0], [2, 1]], [[0, 0], [2, 2]], [[0, 1], [0, 0]], [[0, 1], [0, 1]], [[0, 1], [0, 2]], [[0, 1], [1, 0]], [[0, 1], [1, 1]], [[0, 1], [1, 2]], [[0, 1], [2, 0]], [[0, 1], [2, 1]], [[0, 1], [2, 2]], [[0, 2], [0, 0]], [[0, 2], [0, 1]], [[0, 2], [0, 2]], [[0, 2], [1, 0]], [[0, 2], [1, 1]], [[0, 2], [1, 2]], [[0, 2], [2, 0]], [[0, 2], [2, 1]], [[0, 2], [2, 2]], [[1, 0], [0, 0]], [[1, 0], [0, 1]], [[1, 0], [0, 2]], [[1, 0], [1, 0]], [[1, 0], [1, 1]], [[1, 0], [1, 2]], [[1, 0], [2, 0]], [[1, 0], [2, 1]], [[1, 0], [2, 2]], [[1, 1], [0, 0]], [[1, 1], [0, 1]], [[1, 1], [0, 2]], [[1, 1], [1, 0]], [[1, 1], [1, 1]], [[1, 1], [1, 2]], [[1, 1], [2, 0]], [[1, 1], [2, 1]], [[1, 1], [2, 2]], [[1, 2], [0, 0]], [[1, 2], [0, 1]], [[1, 2], [0, 2]], [[1, 2], [1, 0]], [[1, 2], [1, 1]], [[1, 2], [1, 2]], [[1, 2], [2, 0]], [[1, 2], [2, 1]], [[1, 2], [2, 2]], [[2, 0], [0, 0]], [[2, 0], [0, 1]], [[2, 0], [0, 2]], [[2, 0], [1, 0]], [[2, 0], [1, 1]], [[2, 0], [1, 2]], [[2, 0], [2, 0]], [[2, 0], [2, 1]], [[2, 0], [2, 2]], [[2, 1], [0, 0]], [[2, 1], [0, 1]], [[2, 1], [0, 2]], [[2, 1], [1, 0]], [[2, 1], [1, 1]], [[2, 1], [1, 2]], [[2, 1], [2, 0]], [[2, 1], [2, 1]], [[2, 1], [2, 2]], [[2, 2], [0, 0]], [[2, 2], [0, 1]], [[2, 2], [0, 2]], [[2, 2], [1, 0]], [[2, 2], [1, 1]], [[2, 2], [1, 2]], [[2, 2], [2, 0]], [[2, 2], [2, 1]], [[2, 2], [2, 2]]]
例如,如果我只想修改第二个列表第二项中的第二个值:

print(mecs_states[1], '-', mecs_states[1][1], '-', mecs_states[1][1][1])

mecs_states[1][1][1] = 'A'
不仅更改所需的值,还将其他值列在同一索引位置

out: [[[0, 0], [0, 0]], [[0, 0], [0, 'A']], [[0, 0], [0, 2]], [[0, 0], [1, 0]], [[0, 0], [1, 1]], [[0, 0], [1, 2]], [[0, 0], [2, 0]], [[0, 0], [2, 1]], [[0, 0], [2, 2]], [[0, 'A'], [0, 0]], [[0, 'A'], [0, 'A']], [[0, 'A'], [0, 2]], [[0, 'A'], [1, 0]], [[0, 'A'], [1, 1]], [[0, 'A'], [1, 2]], [[0, 'A'], [2, 0]], [[0, 'A'], [2, 1]], [[0, 'A'], [2, 2]], [[0, 2], [0, 0]], [[0, 2], [0, 'A']], [[0, 2], [0, 2]], [[0, 2], [1, 0]], [[0, 2], [1, 1]], [[0, 2], [1, 2]], [[0, 2], [2, 0]], [[0, 2], [2, 1]], [[0, 2], [2, 2]], [[1, 0], [0, 0]], [[1, 0], [0, 'A']], [[1, 0], [0, 2]], [[1, 0], [1, 0]], [[1, 0], [1, 1]], [[1, 0], [1, 2]], [[1, 0], [2, 0]], [[1, 0], [2, 1]], [[1, 0], [2, 2]], [[1, 1], [0, 0]], [[1, 1], [0, 'A']], [[1, 1], [0, 2]], [[1, 1], [1, 0]], [[1, 1], [1, 1]], [[1, 1], [1, 2]], [[1, 1], [2, 0]], [[1, 1], [2, 1]], [[1, 1], [2, 2]], [[1, 2], [0, 0]], [[1, 2], [0, 'A']], [[1, 2], [0, 2]], [[1, 2], [1, 0]], [[1, 2], [1, 1]], [[1, 2], [1, 2]], [[1, 2], [2, 0]], [[1, 2], [2, 1]], [[1, 2], [2, 2]], [[2, 0], [0, 0]], [[2, 0], [0, 'A']], [[2, 0], [0, 2]], [[2, 0], [1, 0]], [[2, 0], [1, 1]], [[2, 0], [1, 2]], [[2, 0], [2, 0]], [[2, 0], [2, 1]], [[2, 0], [2, 2]], [[2, 1], [0, 0]], [[2, 1], [0, 'A']], [[2, 1], [0, 2]], [[2, 1], [1, 0]], [[2, 1], [1, 1]], [[2, 1], [1, 2]], [[2, 1], [2, 0]], [[2, 1], [2, 1]], [[2, 1], [2, 2]], [[2, 2], [0, 0]], [[2, 2], [0, 'A']], [[2, 2], [0, 2]], [[2, 2], [1, 0]], [[2, 2], [1, 1]], [[2, 2], [1, 2]], [[2, 2], [2, 0]], [[2, 2], [2, 1]], [[2, 2], [2, 2]]]
我错过了什么?我需要列表中的每个列表都是独立的。我猜原因在于itertools的产品,但我不完全理解为什么


解决方案是什么?

当您构建
mecs\u州
列表时,您不是在创建新的内部列表,而是在引用您在
mec\u州
中创建的相同列表。作为一个较小的例子:

导入itertools
nums=[1,2]
pairs=[itertools.product(nums,repeat=2)中p的列表(p)]
#配对=[[1,1],[1,2],[2,1],[2,2]]
a、 b,c,d=成对#为后面的示例解包“成对”。
nested=[itertools.product(成对,重复=2)中p的列表(p)]
#嵌套=[
#     [[1, 1], [1, 1]],
#     [[1, 1], [1, 2]],
#     [[1, 1], [2, 1]],
#     [[1, 1], [2, 2]],
# ...]
嵌套的
的内部元素的一点是,通过引用,它们与
对的元素是相同的列表:

nested[0][0]是一个
#真的
嵌套的[0][1]是一个
#真的
嵌套的[0][0][0]=“x”
#a=['x',1]
#嵌套=[
#[x',1],[x',1]],
#[x',1],[x',2]],
#[x',1],[2,1],,
#[x',1],[2,2],,
# ...]
因此,当您修改
nested[0][0][0]
时,即修改
nested[0][0]
a
都指向的列表。从本质上讲,这是人们在执行
[[]]*10
时遇到的问题的一个稍微复杂的版本,所有十个列表在内存中都是相同的列表


您可以在构建集合后,等到最后,将
itertools.product
提供给您的
tuple
s转换为
list
s来解决这个问题。但是,一旦您进入嵌套集合的深度超过了两个级别,就应该开始考虑类或其他数据结构是否更适合封装所需的行为。

当您构建
mecs\U状态
列表时,您并不是在创建新的内部列表,您正在引用在
mec\u capacity\u州创建的相同列表。作为一个较小的例子:

导入itertools
nums=[1,2]
pairs=[itertools.product(nums,repeat=2)中p的列表(p)]
#配对=[[1,1],[1,2],[2,1],[2,2]]
a、 b,c,d=成对#为后面的示例解包“成对”。
nested=[itertools.product(成对,重复=2)中p的列表(p)]
#嵌套=[
#     [[1, 1], [1, 1]],
#     [[1, 1], [1, 2]],
#     [[1, 1], [2, 1]],
#     [[1, 1], [2, 2]],
# ...]
嵌套的
的内部元素的一点是,通过引用,它们与
对的元素是相同的列表:

nested[0][0]是一个
#真的
嵌套的[0][1]是一个
#真的
嵌套的[0][0][0]=“x”
#a=['x',1]
#嵌套=[
#[x',1],[x',1]],
#[x',1],[x',2]],
#[x',1],[2,1],,
#[x',1],[2,2],,
# ...]
因此,当您修改
nested[0][0][0]
时,即修改
nested[0][0]
a
都指向的列表。从本质上讲,这是人们在执行
[[]]*10
时遇到的问题的一个稍微复杂的版本,所有十个列表在内存中都是相同的列表

您可以在构建集合后,等到最后,将
itertools.product
提供给您的
tuple
s转换为
list
s来解决这个问题。但是,一旦您进入嵌套集合的深度超过了几层,就应该开始考虑类或其他数据结构是否更适合封装所需的行为。

只需“克隆”mecs_状态列表项即可。请参见代码中的
copy.deepcopy

import itertools
import copy

NUM_MECS = 2
MAX_MEC_CAPACITY = 2
VNF_TYPES = 2

# Mec capacity to hold a vnf
served_vnfs = list(range(MAX_MEC_CAPACITY + 1))  # 0 does not  count as capacity
# All possible mec states as far as holded vnfs
mec_capacity_states = [list(s) for s in itertools.product(served_vnfs, repeat=VNF_TYPES)]
# All possible states with defined number of mecs
mecs_states = [copy.deepcopy(list(p)) for p in itertools.product(mec_capacity_states, repeat=NUM_MECS)]
print(mecs_states)
print(mecs_states[1], '-', mecs_states[1][1], '-', mecs_states[1][1][1])
mecs_states[1][1][1] = 'A'
print(mecs_states)
