What is the recommended way to use Vim folding for Python code

Question

I am interested in enabling code folding in Vim for Python code. I have noticed multiple ways to do so.

Does anyone have a preferred way to do Python code folding in

Answer 1

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 fo :call ToggleFold()
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)
