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

In your .vimrc:

set foldmethod=indent
set shiftwidth=4

Then zM to mask all zR to expand all. I also added:

nnoremap  za
vnoremap  zf
map z1  :set foldlevel=0
map z2  :set foldlevel=1
map z3  :set foldlevel=2
map z4  :set foldlevel=3
map z5  :set foldlevel=4
map z6  :set foldlevel=5
map z7  :set foldlevel=6
map z8  :set foldlevel=7
map z9  :set foldlevel=8

So you can z1 and z2 to unindent little by little.
