Multiple imports on the same line can increase costs

This code insight counts one violation if an “import” not preceded by a “from” contains several arguments.


import os, sys


import os
import sys
from xxx import a, b


Why you should care

Imports should usually be on separate lines, e.g.:

Yes: import os
     import sys

No:  import sys, os

It’s okay to say this though:

from subprocess import Popen, PIPE

Business Impacts

It is recommended to avoid these in order to ensure the code is more readable and cost effective.
