Changes from the original python.vim are:

  • Added support for Python 3 syntax highlighting
  • Added :Python2Syntax and :Python3Syntax commands which allow to switch between Python 2 and Python 3 syntaxes respectively without reloads/restarts
  • Updated strings highlighting
  • Enhanced special symbols highlighting inside strings
  • Enhanced highlighting of numeric constants
  • Added optional highlighting for %-formatting inside strings
  • Added highlighting for magic comments: source code encoding and #! (executable) strings
  • Added highlighting for new exceptions and builtins
  • Added highlighting for doctests
  • Added highlighting for new @decorator syntax introduced in Python 2.4a2
  • Added highlighting for the following errors:
    • invalid symbols in source file
    • mixing spaces and tabs
    • invalid numeric constants
    • invalid %-formatting inside strings
    • invalid variable names
    • trailing spaces (triggered by the python_highlight_space_errors option)

Some of these features was later backported into the original python.vim.

How to install

The easiest installation method is to place syntax/python.vim script into your ~/.vim/syntax/ directory.

You can also use Pathogen or Vundle plugin managers in which case you can install the whole python.vim repository into the corresponding plugins directory.

Script options

There are two commands to enable or disable an option:

:let OPTION_NAME = 1
Enable option
:let OPTION_NAME = 0
Disable option

For example to enable all syntax highlighting features you can place the following command in your ~/.vimrc script:

let python_highlight_all = 1

Option and commands to select Python version
