在ini文件中使用JSON路径

Question

I want to read the json values from config json file. The json object path I use in my python code is like below:

jsonfile['Data'][0]['Tenants'][0]['TenPropertyGroup']

Now I want to pass this above path "['Data'][0]['Tenants'][0]['TenPropertyGroup']" from ini file to make sure I can make changes in ini file if the object path gets changed in json file.

My config.ini looks like:

[CONFIG]
TenPropertyGroup= ['Data'][0]['Tenants'][0]['TenPropertyGroups']

My python code after reading from ini file looks like

globalconfig = "config.ini"
config = configparser.ConfigParser()
config.read(globalconfig)

f = open(configfile, )
jsonfile = json.load(f)

TenPropertyGroup = config['CONFIG']['TenPropertyGroup']

TenPropertyGroups = (str(jsonfile ) + TenPropertyGroup)

But when I am reading in Python using configparser the above PropertyGroup is of string data type and I am not able to get the list from json file.

I am trying to read this ini properly from python code but not able to convert it to object.

I would suggest a different approach. You should avoid executing text read from a file for security reasons. If you use a different format for you ini file value, you could parse it and use the values to drill down into you json object. Here's a simple example:

path_from_ini = 'x/y/z'

json_dict = { 'x' : { 'y' : { 'z' : 42 } } }

parts = path_from_ini.split('/')
v = json_dict

# Drill down into the JSON dictonary
for p in parts:
    v = v[p]

print(v)
