Running PEP8 checks from Python

Question

I can not run PEP8 checks from a Python script.

I don't want explicitly run pep8.exe, because I want to automate this checks, and pep8 executable can lay in different places on different platforms.

Answer 1

PEP8 advanced usage covers using pep8 inside Python script.

Quoting an example:

import unittest
import pep8


class TestCodeFormat(unittest.TestCase):

    def test_pep8_conformance(self):
        """Test that we conform to PEP8."""
        pep8style = pep8.StyleGuide(quiet=True)
        result = pep8style.check_files(['file1.py', 'file2.py'])
        self.assertEqual(result.total_errors, 0,
                         "Found code style errors (and warnings).")
