pycodestyle 2.12.1

Description:

pycodestyle 2.12.1

pycodestyle is a tool to check your Python code against some of the style
conventions in PEP 8.

Note
This package used to be called pep8 but was renamed to pycodestyle
to reduce confusion. Further discussion can be found in the issue where
Guido requested this
change, or in the
lightning talk at PyCon 2016 by @IanLee1521:

Features

Plugin architecture: Adding new checks is easy.
Parseable output: Jump to error location in your editor.
Small: Just one Python file, requires only stdlib. You can use just
the pycodestyle.py file for this purpose.
Comes with a comprehensive test suite.



Installation
You can install, upgrade, and uninstall pycodestyle.py with these commands:
$ pip install pycodestyle
$ pip install --upgrade pycodestyle
$ pip uninstall pycodestyle
There’s also a package for Debian/Ubuntu, but it’s not always the
latest version.


Example usage and output
$ pycodestyle --first optparse.py
optparse.py:69:11: E401 multiple imports on one line
optparse.py:77:1: E302 expected 2 blank lines, found 1
optparse.py:88:5: E301 expected 1 blank line, found 0
optparse.py:347:31: E211 whitespace before '('
optparse.py:357:17: E201 whitespace after '{'
optparse.py:472:29: E221 multiple spaces before operator
You can also make pycodestyle.py show the source code for each error, and
even the relevant text from PEP 8:
$ pycodestyle --show-source --show-pep8 testing/data/E40.py
testing/data/E40.py:2:10: E401 multiple imports on one line
import os, sys
^
Imports should usually be on separate lines.

Okay: import os\nimport sys
E401: import sys, os
Or you can display how often each error was found:
$ pycodestyle --statistics -qq Python-2.5/Lib
232 E201 whitespace after '['
599 E202 whitespace before ')'
631 E203 whitespace before ','
842 E211 whitespace before '('
2531 E221 multiple spaces before operator
4473 E301 expected 1 blank line, found 0
4006 E302 expected 2 blank lines, found 1
165 E303 too many blank lines (4)
325 E401 multiple imports on one line
3615 E501 line too long (82 characters)
