Storing application settings in Python

I am looking for a smart way to store my settings in Python. All I want to do is to set some parameters and use it in the code.

I found this Best practices for storing settings and this Storing application settings in C# but I don't think that helps me to solve my problem. I want store some parameters for example age weight and name etc. and access them easily.

Is there any best practice?

Pickle it, you can store any python data structure in file and load it later

import pickle
data = dict(user='Homer', age=45, brain=None)

#save data to file
with open('setting.cfg', 'wb') as f: 
            pickle.dump(data, f)

#load data from file
with open('setting.cfg', 'rb') as f: 
            data = pickle.load(f)

I think one way to do that is to store your parameters in a class.

Like this:

class Settings:

    # default settings
    name = 'John'
    surname = 'Doe'
    age = 45
    gender = 'Male'

Another way is to store these variables in a configuration file and then read from it. But I find the former a lot more easier because you can access in your code easier.

Like this:

from settings import *
settings = Settings()
username = settings.name

If you like windows .ini file format, Python comes with ConfigParser (python3 configparser) to interpret them. The doc makes this look more complicated than it is - skip to the end for a simple example.

You can also use (abuse?) import, to load a settings.py file.

Putting your parameters in a class is good. You can add load and save methods to read / overrride defaults from a config file (if it exists) and to create/update a config file using the current values.
