Question

I need to read the file like below:

config = {
    'name': 'hello',
    'see?': 'world'
}

using keys like name and see? ,but I don’t want to hard code the values in script.And how to deal with more deep nesting in this case.The file may contain more sections like this how can I recognize that ‘name’ belongs to which section at runtime.

If you encode your structure as JSON data, as I think you want and you did in the example, you just need to write and read the structure in a file.
As an example:

 import json 
 config = {
  'name': 'hello',
  'see?': 'world'
 }
 out = open('config.json','w')
 out.write(json.dumps(config))
 out.close() 

Configuration file saved

 input = open('config.json','r')
 config = json.loads(input.read())
 input.close()
 print config

Configuration file reloaded
