name 'get_config' is not defined, config parser

[zer0]

Hello, I was just testing changing values in .ini files.
I read forums and most people were saying that configparser is the best module to do so.
I've read on some forums and I wanted to try to do it myself
But this error comes out:

Error:
Traceback (most recent call last):
  File "C:\Users\P1tey\Desktop\test.py", line 10, in <module>
    update_setting("C:\\Users\\P1tey\\Desktop\\tests.ini", "Testsection", "resolutiony", "1440 x 1080")
  File "C:\Users\P1tey\Desktop\test.py", line 5, in update_setting
    config = get_config(path)
NameError: name 'get_config' is not defined

Here is the code:

import configparser
import os

def update_setting(path, section, setting, value):
    config = get_config(path)
    config.set(section, setting, value)
    with open(path, "wb") as config_file:
        config.write(config_file)

update_setting("C:\\Users\\P1tey\\Desktop\\tests.ini", "Testsection", "resolutiony", "1440 x 1080")

And also, is there any more effective way to do the same thing?

do you mean config.get ?
there is no get_config
