error in python script (for energy meter)

[br0ken]

is the file name indeed config.py? it is expecting just config

ps: config is located in etc/smaemd/

After renaming it I get the following error:

sudo python sma-daemon.py

Error:
Traceback (most recent call last):
  File "sma-daemon.py", line 23, in <module>
    from configparser import SafeConfigParser
ImportError: No module named configparser

sudo python3 sma-daemon.py

Error:
Traceback (most recent call last):
  File "/usr/local/lib/python3.5/configparser.py", line 1136, in _unify_values
    sectiondict = self._sections[section]
KeyError: '[SMA-EM]'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "sma-daemon.py", line 30, in <module>
    smaemserials=parser.get('[SMA-EM]', 'serials')
  File "/usr/local/lib/python3.5/configparser.py", line 779, in get
    d = self._unify_values(section, vars)
  File "/usr/local/lib/python3.5/configparser.py", line 1139, in _unify_values
    raise NoSectionError(section)
configparser.NoSectionError: No section: '[SMA-EM]'

[inline]sudo systemctl daemon-reload
sudo systemctl enable smaemd.service
sudo systemctl start smaemd.service[/inline]
