" Vim syntax file
" Language: Python
" Maintainer: Zvezdan Petkovic <zpetkovic@acm.org>
" Last Change: 2015 Jun 19
" Credits: Neil Schemenauer <nas@python.ca>
" Dmitry Vasiliev
"
" This version is a major rewrite by Zvezdan Petkovic.
"
" - introduced highlighting of doctests
" - updated keywords, built-ins, and exceptions
" - corrected regular expressions for
"
" * functions
" * decorators
" * strings
" * escapes
" * numbers
" * space error
"
" - corrected synchronization
" - more highlighting is ON by default, except
" - space error highlighting is OFF by default
"
" Optional highlighting can be controlled using these variables.

" Keep Python keywords in alphabetical order inside groups for easy
" comparison with the table in the 'Python Language Reference'
" http://docs.python.org/reference/lexical_analysis.html#keywords.
" Groups are in the order presented in NAMING CONVENTIONS in syntax.txt.
" Exceptions come last at the end of each group (class and def below).
"
" Keywords 'with' and 'as' are new in Python 2.6
" (use 'from __future__ import with_statement' in Python 2.5).
"
" Some compromises had to be made to support both Python 3.0 and 2.6.
" We include Python 3.0 features, but when a definition is duplicated,
" the last definition takes precedence.
"
" - 'False', 'None', and 'True' are keywords in Python 3.0 but they are
" built-ins in 2.6 and will be highlighted as built-ins below.
" - 'exec' is a built-in in Python 3.0 and will be highlighted as
" built-in below.
" - 'nonlocal' is a keyword in Python 3.0 and will be highlighted.
" - 'print' is a built-in in Python 3.0 and will be highlighted as
" built-in below (use 'from __future__ import print_function' in 2.6)
