What is the recommended way to use vim folding for python coding

I am interested in enabling code folding in vim for python coding.

I have noticed multiple ways to do so.

Does anyone have a preferred way to do python code folding in vim?
I.e,

• do you have a particular vim plugin that you use and like?
• do you use manual folding or do you place markers in comments?
• any other recommended ways to do code folding for python in vim?

From stackoverflow

• To be honest folding is one of the vim features I haven't quite used. I tend to use split panes alot more, you can access them with

  :split
  

  and

  :vsplit
  

  And move around them with

  ctrl+w
  

  By default the split pane contains the same buffer that is currently in focus, but you can also open another buffer in it:

  :split otherbuffer
  

  I usually open two panes for the same file when I'm working on different sections of it, so I effectively use that in lieu of folding.

  I realize this answer is slightly offtopic, but I thought you might find the tip on split panes useful.

• Python is well suited for folding on indent, bit for writing my own code I use markers as they can crunch a document down the way you want it and can serve as a kind of a table of contents. I have this in my vimrc to flip between the two when I'm viewing someone elses code.

  #Toggle fold methods \fo
  let g:FoldMethod = 0
  map <leader>fo :call ToggleFold()<cr>
  fun! ToggleFold()
      if g:FoldMethod == 0
          exe 'set foldmethod=indent'
          let g:FoldMethod = 1
      else
          exe 'set foldmethod=marker'
          let g:FoldMethod = 0
      endif
  endfun
  #Add markers (trigger on class Foo line)
  nnoremap ,f2 ^wywO#<c-r>0 {{{2<esc>
  nnoremap ,f3 ^wywO#<c-r>0 {{{3<esc> 
  nnoremap ,f4 ^wywO#<c-r>0 {{{4<esc>
  nnoremap ,f1 ^wywO#<c-r>0 {{{1<esc>
  

• I really like this this plugin.

  Paul D. Eden : Unfortunately, this plugin uses more processor time than I would prefer (even with the a version) as I like to keep my vim speedy. Any other suggestions?

• Try this plugin:

• Personally I can't convince myself to litter my code with the markers. I've become pretty used to (and efficient) at using indent-folding. Together with my mapping of space bar (see below) to open/close folds and the zR and zM commands, I'm right at home. Perfect for Python!

  nnoremap <space> za

  vnoremap <space> zf

  tmadsen : :set foldmethod=indent first. I was googling for just this and stumbled upon your answer, very nice! :)

• I use this syntax file for Python. It sets the folding method to syntax and folds all classes and functions, but nothing else.

• The Python source comes with a vim syntax plugin along with a custom vimrc file. Check the python FAQ on vim

• I wrote my own python ftplugin -- habamax.ru/blog/2009/05/python-folding-in-vim/

  It could be slow as it uses 'expr' foldmethod which is slow by default.

• I think that indent folding is fine for python. I'm making a multi-branched git repo for vim-config python/django IDE ideas. Fork away!
