pep8 - Python style guide checker
pep8 is a tool to check your Python code against some of the style conventions
in PEP 8_.
.. _PEP 8: http://www.python.org/dev/peps/pep-0008/
Mailing List
http://groups.google.com/group/pep8
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
pep8.py file for this purpose - Easy_installable, of course!
Installation
Just an easy_install pep8 ought to do the trick.
Example usage and output
::
$ pep8 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:222:34: W602 deprecated form of raising exception
optparse.py:347:31: E211 whitespace before '('
optparse.py:357:17: E201 whitespace after '{'
optparse.py:472:29: E221 multiple spaces before operator
optparse.py:544:21: W601 .has_key() is deprecated, use 'in'
You can also make pep8.py show the source code for each error, and
even the relevant text from PEP 8::
$ pep8 --show-source --show-pep8 testsuite/E111.py
testsuite/E111.py:2:3: E111 indentation is not a multiple of four
print x
^
Use 4 spaces per indentation level.
For really old code that you don't want to mess up, you can
continue to use 8-space tabs.
Or you can display how often each error was found::
$ pep8 --statistics -qq --filename=*.py 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)
612 W601 .has_key() is deprecated, use 'in'
1188 W602 deprecated form of raising exception
Quick help is available on the command line::
$ pep8 -h
Usage: pep8.py [options] input ...
Options:
-h, --help show this help message and exit
-v, --verbose print status messages, or debug with -vv
-q, --quiet report only file names, or nothing with -qq
--exclude=patterns exclude files or directories which match these comma
separated patterns (default: .svn,CVS,.bzr,.hg,.git)
--filename=patterns when parsing directories, only check filenames matching
these comma separated patterns (default: *.py)
--ignore=errors skip errors and warnings (e.g. E4,W)
--repeat show all occurrences of the same error
--show-source show source code for each error
--show-pep8 show text of PEP 8 for each error
--statistics count errors and warnings
--count count total number of errors and warnings
--benchmark measure processing speed
--testsuite=dir run regression tests from dir
--doctest run doctest on myself
