This is an enhanced version of the original Python syntax highlighting script. Based on python.vim from Vim 6.1 distribution by Neil Schemenauer.

• Added support for Python 3 syntax highlighting
• Added commands Python2Syntax and Python3Syntax commands which allow to switch between Python 2 and Python 3 syntaxes respectively without reloads/restarts
• Updated string 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)

Folding is done by the plugin SimpylFold.

Use one of the following plugin managers:

• dein
• vim-plug
• vundle
• pathogen

Or you can just manually place syntax/python.vim into ~/.config/nvim/syntax/ or ~/.vim/syntax/.

Enable option with:

let VARIABLE = 1

Disable option with:

let VARIABLE = 0

For example to enable all syntax highlighting features you can add the following command to your ~/.config/nvim/init.vim or ~/.vimrc:

let g:python_highlight_all = 1

Variables:

g:python_version_2 or b:python_version_2

Enable highlighting for Python 2 (Python 3 highlighting is enabled by default).
