How to read a config file with Python's configparser?

I'm working on reading an external config file in Python(3.7) using the module configparser.

Here is my sample configuration file config.ini

[ABC]
ch0 = "C:/Users/utility/ABC-ch0.txt"
ch1 = "C:/Users/utility/ABC-ch1.txt"

[settings]
script = "C:/Users/OneDrive/utility/xxxx.exe"
settings = "C:/Users/OneDrive/xxxxxxConfig.xml"

Here is the sample code I tried:

import configparser
config = configparser.ConfigParser()

config.read('config.ini')
ch0 = config.get('ABC','ch0')
print(ch0)

And here is the error code I am getting, not sure what I am doing wrong:

NoSectionError: No section: 'ABC'

Any help is much appreciated. Thanks in advance.

Your code is absolutely fine.

This line:

config.read('config.ini')

tries to read the file from the same directory as the .py file you're running. So you have 3 options:

1. move the config.ini file to be next to the .py file
2. use a correct relative path when reading the file (see: https://stackoverflow.com/a/78458469/9835872 for how to do this well)
3. use an absolute path when reading the file (not recommended for portability reasons)
