How can I use Emacs Flymake mode for python with pyflakes and pylint checking code?

Question

For checking code in python mode I use flymake with pyflakes

Also I want check code style (pep8) with pylint (description on the same page with pyflakes)

This solutions work. But I can't configure flymake for work with pyflakes and pylint together. How can I do it?

Well, flymake is just looking for a executable command thats output lines in a predefined format. You can make a shell script for example that will call successively all the checkers you want...

You must also make sure that your script ends by returning errorlevel 0. So this is an example:

This is what I've done in a "pycheckers" script:

#!/bin/bash

epylint "$1" 2>/dev/null
pyflakes "$1"
pep8 --ignore=E221,E701,E202 --repeat "$1"
true

For the emacs lisp part:

(when (load "flymake" t)
  (defun flymake-pyflakes-init ()
    (let* ((temp-file (flymake-init-create-temp-buffer-copy
                       'flymake-create-temp-inplace))
           (local-file (file-relative-name
                        temp-file
                        (file-name-directory buffer-file-name))))
      (list "pycheckers"  (list local-file))))
  (add-to-list 'flymake-allowed-file-name-masks
               '("\\.py\\'" flymake-pyflakes-init)))
