Python3.6: File "/usr/lib/python3.6/configparser.py", line 1138, in _unify_values

Question

My script is working fine on Pycharm with python 3.6, but has some issues when i run from ubuntu 16 using Python3.6

Error:

Here the path provided in the variable 'configfilename' is not pointing towards the exact location of config.ini file. Default directories can be different according to the environments/servers/modules/etc; which is not the directory in which your program exists. So, you can make the code point towards the current directory where the file exists.

You can try by importing OS module(import os) and following changes in your variable 'configfilename' which directs to 'config.ini' file under the directory 'resources'.

configfilename = (os.path.join(os.path.dirname(__file__),'resources','config.ini'))
