it took me quite a while to figure out why the code below
from ConfigParser import ConfigParser conf = ConfigParser() conf.read(...)
was working in one codebase but not working in another codebase.
Turns out the package renamed to lower case (probably backward compatibility is never a concern in python ecosystem) in python3.
so above code worked for python 2, need to change to below for python 3
from configparser import ConfigParser conf = ConfigParser() conf.read(...)
(wondering how python ecosystem would look like if there is a version 4/5 in future).
