I tried to use configparser module from standard library in python 3.6 or python 3.5.1
My ini file looks like this:
[common]
domain = http://some_domain_name:8888
about = about/
loginPath = /accounts/login/?next=/home
fileBrowserLink = /filebrowser
partNewDirName = some_dir
[HUE_310]
partNewFilePath = ${common:domain}
My "main" program looks like this:
from configparser import ConfigParser
parser = ConfigParser()
parser.read('configfile.ini')
lll = parser.get('HUE_310', 'partNewFilePath')
print(lll)
Instead http://some_domain_name:8888 I got ${common:domain}
I use Pycharm Community as my IDE. I use virtualenv.
I have no idea what is wrong with my code...

Extended interpolation is using ${section:option} to denote a value from a foreign section. Interpolation can span multiple levels. For convenience, if the section: part is omitted, interpolation defaults to the current section (and possibly the default values from the special section).
A Python configuration file is a pure Python file that populates a configuration object. This configuration object is a Config instance.
configparser comes from Python 3 and as such it works well with Unicode.
Read and parse one configuration file, given as a file object. Read configuration from a given string. Read configuration from a dictionary. Keys are section names, values are dictionaries with keys and values that should be present in the section.
If you want extended interpolation, you have to create an instance of the configparser.ExtendedInterpolation class, by calling it, and then using that with the interpolation= keyword argument when you create the ConfigParser instance as shown below:
from configparser import ConfigParser, ExtendedInterpolation
parser = ConfigParser(interpolation=ExtendedInterpolation())
parser.read('configfile.ini')
lll = parser.get('HUE_310', 'partNewFilePath')
print(lll) # -> http://some_domain_name:8888
