I have a list:

list = ['aaazzz0', 'aaazzz1', 'aaazzz2', 'aaazzz3', 'aaazzz4', 'aaazzz5', 'bbbzzz0', 'bbbzzz0', 'bbbzzz1','bbbzzz2','bbbzzz3','bbbzzz4','bbbxxx0','bbbxxx1','bbbxxx2','bbbxxx3']

my desired state is:

`

{
  "aaa": {
    "zzz": [
      "aaazzz0",
      "aaazzz1",
      "aaazzz2",
      "aaazzz3",
      "aaazzz4",
      "aaazzz5"
    ]
  },
  "bbb": {
    "zzz": [
      "bbbzzz0",
      "bbbzzz1",
      "bbbzzz2",
      "bbbzzz3",
      "bbbzzz4"
    ],
    "xxx": [
      "bbbxxx0",
      "bbbxxx1",
      "bbbxxx2",
      "bbbxxx3"
    ]
  }
}

`

my code is:

`

import re, json

list = ['aaazzz0', 'aaazzz1', 'aaazzz2', 'aaazzz3', 'aaazzz4', 'aaazzz5', 'bbbzzz0', 'bbbzzz0', 'bbbzzz1','bbbzzz2','bbbzzz3','bbbzzz4','bbbxxx0','bbbxxx1','bbbxxx2','bbbxxx3']

regex = '^.{3}([a-z]{3})'

all_dict = {}
a = {}
a_list = []
b = {}
b_list = []

for item in list:
    end_match = re.findall(regex, item)[0]
    aaa_match = re.search('aaa', item)
    bbb_match = re.search('bbb', item)
    for suffix in end_match:

        if aaa_match:
            a[suffix] = []
            a_list.append(item)
            a[suffix] = a_list

        elif bbb_match:
            b[suffix] = []
            b_list.append(item)
            b[suffix] = b_list



all_dict["aaa"] = a
all_dict["bbb"] = b

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

`

so zzz, xxx keys I need to generate dynamicaly based on what is in list element, it's always 4,5,6 char.

this code genearetes the following output, which is not what I'm looking for

`

{
    "aaa": {
        "z": [
            "aaazzz0",

I stuck... with my code

CodePudding user response：

I think this code will do the trick:

lst = ['aaazzz0', 'aaazzz1', 'aaazzz2', 'aaazzz3', 'aaazzz4', 'aaazzz5', 'bbbzzz0', 'bbbzzz0', 'bbbzzz1', 'bbbzzz2',
       'bbbzzz3', 'bbbzzz4', 'bbbxxx0', 'bbbxxx1', 'bbbxxx2', 'bbbxxx3']

new_dict_result = {"aaa": {},
                   "bbb": {}
                   }

for item in lst:
    first_letter = item[0]
    first_three_letters = first_letter * 3
    last_three_letters = item[3:6]
    new_dict_result[first_three_letters].setdefault(last_three_letters, [])
    if item not in new_dict_result[first_three_letters][last_three_letters]:
        new_dict_result[first_three_letters][last_three_letters].append(item)

print(new_dict_result)

Good luck !
