I have a Python script that generates a mapping JSON based off a JSON template.

The script reads the JSON template, then compares a folder structure that has to match the template, so that it can output a new JSON with corresponding values.

This is an example of a line in the JSON template.

"path_structure": "Folder/Apples/{apple_ids}/*",

Then, the script will receive a folder structure like so:

Folder/
└── Apples/
    ├── 43952/
    ├── 53453/
    ├── 12342/
    └── 76552/

The resulting separate JSONs from the script would have the lines:

"value": "43952"

"value": "53453"

"value": "12342"

"value": "76552"

The script looks like this right now.

def get_relative_path(file, start_dir):
  relative_path = os.path.relpath(file, start=start_dir)
  return os.path.normpath(relative_path).split(os.sep)

file_components = get_relative_path(file, start_dir)

def get_path_components(mapping_file_json):
  path_structure = mapping_file_json["path_structure"].rstrip("/*")
  return path_structure.split("/")

path_components = get_path_components(mapping_file_json)

def get_linking_identifier(path_components):
  linking_identifiers = ["{apple_ids}"]

  for linking_identifier in linking_identifiers:
    try:
      linking_identifier_index = path_components.index(linking_identifier)
      return linking_identifier_index
    except ValueError:
      continue

value = file_components[linking_identifier_index]

"value": str(value)

My inquiry is regarding supporting changing the template structure.

I need to support when the JSON template may look like:

"path_structure": "Folder/Apples/notimportant_{apple_ids}/*"

or

"path_structure": "Folder/Apples/{apple_ids}_random/*"

or

"path_structure": "Folder/Apples/random{apple_ids}words/*"

Example folder structures:

Folder/
└── Apples/
    ├── notimportant_43952/
    ├── notimportant_53453/
    ├── notimportant_12342/
    └── notimportant_76552/

or

Folder/
└── Apples/
    ├── 43952_random/
    ├── 53453_random/
    ├── 12342_random/
    └── 76552_random/

And the outputted search values should still look like:

"value": "43952"

"value": "53453"

"value": "12342"

"value": "76552"

How can I best edit my script to support this new functionality?
