python - What file format to use for Django configuration which can be frequently updated using Django forms -

i have django application need configuration file.

i want key value pairs in there, values can updated using django form fields.

which 1 best file format, read , write easy (user can update values using django form).

i have value below:

<key_max_range>=**<value_max_range>** 

the easiest thing serialize json or yaml. however, if want more human-readable format more strictly set of key-value pairs, might use configparser module. reads , writes ini-style configuration files, this:

[section] key = value 

here example of writing out configuration file based on form's cleaned_data:

in [39]: configparser import safeconfigparser  in [40]: cleaned_data = {'foo': 'bar', 'bob': 'ann'}  in [41]: config = safeconfigparser()  in [42]: config.add_section('my_form')  in [43]: field, value in cleaned_data.iteritems():    ....:     config.set('my_form', field, value)    ....:  in [44]: open('example.cfg', 'w') config_file:    ....:     config.write(config_file)    ....:   in [45]: cat example.cfg [my_form] bob = ann foo = bar
