How and where to store a data for path tree?

[Larz60+]

I use relative path's all the time, using pathlib
I keep all of my paths in one file for each project, and name it ProjectPaths.py (replace 'Project' with actual name, like 'IllinoisPaths.py'
I then usually define paths for each type of file, csv, json, html, txt etc.
Note that the directory will be created if it doesn't exist.
It will not overwrite existing directories of same name.

example:

# BusinessPaths.py

from pathlib import Path
import os


class BusinessPaths:
    def __init__(self):
        os.chdir(os.path.abspath(os.path.dirname(__file__)))
        self.homepath = Path('.')
        self.rootpath = self.homepath / '..'

        self.datapath = self.rootpath / 'data'
        self.datapath.mkdir(exist_ok=True)

        self.dbpath = self.datapath / 'database'
        self.dbpath.mkdir(exist_ok=True)

        self.htmlpath = self.datapath / 'html'
        self.htmlpath.mkdir(exist_ok=True)

        self.idpath = self.datapath / 'Idfiles'
        self.idpath.mkdir(exist_ok=True)
        
        self.jsonpath = self.datapath / 'json'
        self.jsonpath.mkdir(exist_ok=True)

        self.prettypath = self.datapath / 'pretty'
        self.prettypath.mkdir(exist_ok=True)

        self.textpath = self.datapath / 'text'
        self.textpath.mkdir(exist_ok=True)

        self.tmppath = self.datapath / 'tmp'
        self.tmppath.mkdir(exist_ok=True)

        self.base_url = 'http://searchctbusiness.ctdata.org/'

        self.cities_json = self.jsonpath / 'cities.json'
        self.city_list_url = 'https://ctstatelibrary.org/cttowns/counties'
        self.raw_city_file = self.tmppath / 'raw_city.html'
        # self.cities_text = self.textpath / 'cities.txt'

        self.company_master_json = self.jsonpath / 'CompanyMaster.json'

        self.CompanyMasterDb = self.dbpath / 'CompanyMaster.db'

        self.company_main = self.jsonpath / 'CompanyMain.json'
        self.company_detail = self.jsonpath / 'CompanyDetail.json'
        self.company_principals = self.jsonpath / 'CompanyPrincipals.json'
        self.company_agents = self.jsonpath / 'CompanyAgents.json'
        self.company_filings = self.jsonpath / 'CompanyFilings.json'


if __name__ == '__main__':
    BusinessPaths()

So if I want to open a file to dump some data in my json directory into a file names 'mystuff.json' it's as simeple as:

from BusinessPaths import BusinessPaths
import json

sampledict = {
    'one': 1,
    'two': 2,
    'three': 3
}

bpaths = BusinessPaths()

jsonfile = bpaths.jsonpath / 'junk.json'

with jsonfile.open('w') as fp:
    json.dump(sampledict, fp)
