如何在python中创建用于存储目录结构的嵌套字典？

如何解决如何在python中创建用于存储目录结构的嵌套字典？

假设以下目录结构：-

|--apc
|   |--data
|   |   |--datainstaller.zip
|   |   |--rs_details
|   |   |   |--readme.txt
|   |--rem
|   |   |--15.0.x
|   |   |   |--15.0.1
|   |   |   |   |--dataconversion
|   |   |   |   |   |--details.txt
|   |   |   |--15.0.2
|   |   |   |   |--dataconversion
|   |   |   |   |   |--details.txt
|   |   |--alloc_details.txt
|   |--res
|   |   |--resapp.zip
|--REIM
|   |--dataconversion
|   |   |--dataconversioninstaller.zip
|   |   |--rs_details.txt
|   |--reim_bkp.zip
|   |--hotfix
|   |   |--mergedRC
|   |   |   |--alloc
|   |   |   |   |--p231.zip
|--testfile1.txt
|--testfile2.txt

在python列表中作为绝对路径（从根目录开始，以深度优先方式）作为（即，路径以列表中的字符串形式给出）:-

['apc/','apc/data/','apc/data/datainstaller.zip','apc/data/rs_details/','apc/data/rs_details/readme.txt','apc/rem/','apc/rem/15.0.x/','apc/rem/15.0.x/15.0.1/','apc/rem/15.0.x/15.0.1/dataconversion/','apc/rem/15.0.x/15.0.1/dataconversion/details.txt','apc/rem/15.0.x/15.0.2/','apc/rem/15.0.x/15.0.2/dataconversion/','apc/rem/15.0.x/15.0.2/dataconversion/details.txt','apc/rem/alloc_details.txt','apc/res/','apc/res/resapp.zip','REIM/','REIM/dataconversion/','REIM/dataconversion/dataconversioninstaller.zip','REIM/dataconversion/rs_details.txt','REIM/reim_bkp.zip','REIM/hotfix/','REIM/hotfix/mergedRC/','REIM/hotfix/mergedRC/alloc','REIM/hotfix/mergedRC/alloc/p231.zip','testfile1.txt','testfile2.txt']

我想创建一个嵌套字典来存储这个目录结构，就像这样:-

  {
       'apc/': {

                'apc/data/':{
                             'apc/data/datainstaller.zip' : {}
                              'apc/data/rs_details/' : {
                                            'apc/data/rs_details/readme.txt' : {}
                                         }
                          
                'apc/rem/':{
                                'apc/rem/15.0.x' : {
                                                'apc/rem/15.0.x/15.0.1/': { 
                                                                             'apc/rem/15.0.x/15.0.1/dataconversion' : { 'apc/rem/15.0.x/15.0.1/dataconversion/details.txt' : {} }
                                         }
                                                'apc/rem/15.0.x/15.0.2/': { 
                                                                             'apc/rem/15.0.x/15.0.2/dataconversion' : { 'apc/rem/15.0.x/15.0.2/dataconversion/details.txt' : {} }
                                         }
                             }
                       }
             }
   }

我尝试通过使用参数作为路径中 / 的数量并在较低级别的目录路径中查找前缀来迭代地和递归地执行此操作，但它导致嵌套字典不一致，我无法获得如上所示的所需的。

谁能帮我解决这个问题？

[编辑：目录的路径字符串总是以/结尾，而文件的路径字符串不是]

解决方法

这样做：

import os,json

directory_dict = {}

path_list = ['apc/','apc/data/','apc/data/datainstaller.zip','apc/data/rs_details/','apc/data/rs_details/readme.txt','apc/rem/','apc/rem/15.0.x/','apc/rem/15.0.x/15.0.1/','apc/rem/15.0.x/15.0.1/dataconversion/','apc/rem/15.0.x/15.0.1/dataconversion/details.txt','apc/rem/15.0.x/15.0.2/','apc/rem/15.0.x/15.0.2/dataconversion/','apc/rem/15.0.x/15.0.2/dataconversion/details.txt','apc/rem/alloc_details.txt','apc/res/','apc/res/resapp.zip','REIM/','REIM/dataconversion/','REIM/dataconversion/dataconversioninstaller.zip','REIM/dataconversion/rs_details.txt','REIM/reim_bkp.zip','REIM/hotfix/','REIM/hotfix/mergedRC/','REIM/hotfix/mergedRC/alloc','REIM/hotfix/mergedRC/alloc/p231.zip','testfile1.txt','testfile2.txt']

for item in path_list:
    path,filename = os.path.split(item)
    split_path = path.split('/')
    # directory_level is a pointer into the directory_dict
    directory_level = directory_dict
    # current_directory is a string to hold the path name as we build it up again from iterating the split_path list
    current_directory = ''

    for path_item in split_path:
        # build up the current_directory
        current_directory += path_item + '/'
        if current_directory not in directory_level:
            # insert new dictionary at this level
            directory_level[current_directory] = {}
        # set the directory_level pointer to new level
        directory_level = directory_level[current_directory]

    if filename:
        # add the whole item into the dictionary at this level
        directory_level[item] = {}

print(json.dumps(directory_dict,indent=4)) 

和输出：

        "apc/data/": {
            "apc/data/datainstaller.zip": {},"apc/data/rs_details/": {
