如何根据特定条件用另一个列表替换多维数组python中的嵌套列表

Question

我试图在特定条件下替换 my_list 中的嵌套列表。 在这种情况下，我想用第二个列表的元素替换'HB2_DF_en1a' ，如果在前一个列表中找到'' ，则以此类推。 ''和第二个列表中的元素数量相同。

my_list = [[[['', ''], ['HB2_DF_en1a', 'HB2_DF_en2a']]],
           [[[''], ['XY1_DF_en1a']],
            [['Io01[4:2]'], ['XY_DF1']]],
           [[['', ''], ['XY2_DF_en1a', 'XY2_DF_en2a']]]]
2nd_list = [['XY1_IPC'],
            ['cat_lpm'],
            ['XY_ABC1'],
            ['XY2_IPC'],
            ['XY_ABC2', 'XY2_IPC']] 

我在尝试 -

b = 0
for i in my_list:
    for j in i:
        for k in j:
                if a == '':
                    k+1.append(2nd_list[b])
                    b = b+1

我正在寻找的输出 -

my_list = [[[['', ''], [['XY1_IPC'], ['cat_lpm']]]],
           [[[''], ['XY_ABC1']]],
            [['Io01[4:2]'], ['XY_DF1']],
           [[['', ''],
            [['XY2_IPC'], ['XY_ABC2', 'XY2_IPC']]]]]

Answer 1

像这样尝试：

my_list = [
    [[["", ""], ["HB2_DF_en1a", "HB2_DF_en2a"]]],
    [[[""], ["XY1_DF_en1a"]], [["Io01[4:2]"], ["XY_DF1"]]],
    [[["", ""], ["XY2_DF_en1a", "XY2_DF_en2a"]]],
]
reference_list = [
    ["XY1_IPC"],
    ["cat_lpm"],
    ["XY_ABC1"],
    ["XY2_IPC"],
    ["XY_ABC2", "XY2_IPC"],
]


ref_index = 0
for level1 in my_list:
    for level2 in level1:
        for index, value in enumerate(level2):
            if value[0] == "":
                for change_index, times in enumerate(value):
                    level2[1][change_index] = reference_list[ref_index]
                    ref_index = ref_index + 1


# Print result:
print(my_list)

结果：

[
    [
        [
            ['', ''],
            [
                ['XY1_IPC'],
                ['cat_lpm']
            ]
        ]
    ],
    [
        [
            [''],
            [
                ['XY_ABC1']
            ]
        ],
        [
            ['Io01[4:2]'],
            ['XY_DF1']
        ]
    ],
    [
        [
            ['', ''],
            [
                ['XY2_IPC'],
                ['XY_ABC2', 'XY2_IPC']
            ]
        ]
    ]
]
