" Options to control Python syntax highlighting:
"
" For highlighted numbers:
"
"    let python_highlight_numbers = 1
"
" For highlighted builtin functions:
"
"    let python_highlight_builtins = 1
"
" For highlighted standard exceptions:
"
"    let python_highlight_exceptions = 1
"
" Highlight erroneous whitespace:
"
"    let python_highlight_space_errors = 1
"
" If you want all possible Python highlighting (the same as setting the
" preceding options):
"
"    let python_highlight_all = 1

" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
