Go the base location of your source code and activate your virtualenv if any.

$ pip install flake8 # install flake8

If you are using git, create a pre-commit hook file

$ vim .git/hooks/pre-commit

In the file add the below two lines

#!/bin/sh
flake8 .

Now as you try to commit your code it will show you all coding style issues.
You will only be able to commit until code is pep8 compliant.
