How to fix   Many Parameters   

Many Parameters

Methods with many parameters are not only hard to understand, but their parameters also often become inconsistent when you need more, or different data.

There are several approaches to avoid long parameter lists:

1 
# encoding=utf8
2 
# This is temporary fix to import module from parent folder
3 
# It will be removed when package is published on PyPI
4 
import sys
5 
sys.path.append('../')
6 
# End of fix
