PEP check when I open a pyhton code with emacs is so annoying. So I figured out how to disable PEP8 check, and this is how it works.

In the .emacs.d/init.d or appropriate file in your system, python-check-command should be set nil. :

(add-hook 'python-mode-hook
          '(lambda ()
             (seq python-check-command nil)

Then you never be bothered by too strict PEP8 checker.
