Python-mode, Python in VIM

Python-mode is a vim plugin that allows you to use the pylint, rope, pydoc, pyflakes, pep8, mccabe libraries in vim to provide features like python code looking for bugs, refactoring and some other useful things.

This plugin allow you create python code in vim very easily. There is no need to install the pylint, rope or any used python library on your system.

  • Python objects and motion (]], 3[[, ]]M, vaC, viM, daC, ciM, ...)
  • Folding of python code
  • Virtualenv support
  • Highlight syntax errors
  • Highlight and auto fix unused imports
  • Many linters (pylint, pyflakes, ...) that can be run simultaneously
  • Strong code completion
  • Code refactoring
  • Python documentation
  • Run python code
  • Go to definition
  • Powerful customization
  • And more, more ...

See (very old) screencast here: (sorry for quality, this is my first screencast)


## 2012-08-02 0.6.5

  • Updated Pep8 to version 1.3.3
  • Updated Pylint to version 0.25.2
  • Fixed virtualenv support for windows users
  • Added pymode modeline ':help PythonModeModeline'
  • Added diagnostic tool ':call pymode#troubleshooting#Test()'
  • Added PyLintAuto command ':help PyLintAuto'
  • Code checking is async operation now
  • More, more fast the pymode folding
  • Repaired execution of python code


  • VIM >= 7.0 with python support (also --with-features=big if you want use g:pymode_lint_signs)

How to install

Using pathogen (recomended)

% cd ~/.vim
% mkdir -p bundle && cd bundle
% git clone git://
  • Enable pathogen in your ~/.vimrc:

    " Pathogen load
    filetype off
    call pathogen#infect()
    call pathogen#helptags()
    filetype plugin indent on
    syntax on


% git clone git://
% cd python-mode
% cp -R * ~/.vim

Then rebuild helptags in vim:

:helptags ~/.vim/doc/


filetype-plugin (:help filetype-plugin-on) and filetype-indent (:help filetype-indent-on) must be enabled for use python-mode.


If your python-mode dont work, type command:

:call pymode#troubleshooting#Test()

And fix warnings or copy output and send it to me (ex. with github issue).

Also you can see vim help :help PythonModeCommands

Command Description

PyLintCheckerToggle Toggle code checker (pylint, pyflakes)
PyLint Check current buffer
PyLintAuto Automatic fix PEP8 errors
Pyrun Run current buffer in python

Rope completion is very slow

To work rope creates a service directory: .ropeproject. If g:pymode_rope_guess_project set (by default) and .ropeproject in current dir not found, rope scan .ropeproject on every dir in parent path. If rope finded .ropeproject in parent dirs, rope set project for all child dir and scan may be slow for many dirs and files.


  • Disable g:pymode_rope_guess_project to make rope always create .ropeproject in current dir.
  • Delete .ropeproject from dip parent dir to make rope create .ropeproject in current dir.
  • Press <C-x>po or :RopeOpenProject to make force rope create .ropeproject in current dir.

Pylint check is very slow

In some projects pylint may check slowly, because it also scan imported modules if posible. Try use pyflakes, see :h 'pymode_lint_checker'.


You may set exrc and set secure in your vimrc for auto set custom settings from .vimrc from your projects directories. Example: On Flask projects I automaticly set g:pymode_lint_checker = "pyflakes", on django g:pymode_lint_cheker = "pylint"

OSX cannot import urandom


The sequence of commands that fixed this:

brew unlink python
brew unlink macvim
brew remove macvim
brew install -v --force macvim
brew link macvim
brew link python
