How to comment out a block of Python code in Vim
I was wondering if there was any key mapping in Vim to allow me to indent certain lines of code (whether those lines have been selected in visual mode, or n lines above/below current cursor position).
So basically something that converts the following
def my_fun(x, y):
return x + y
to
#def my_fun(x, y):
# return x + y
I am okay with using either # or """ for commenting out the relevant lines. Ideally, I would also like the same keymapping to uncomment the lines if the given lines have been commented out.
Step 1: Go to the the first column of the first line you want to comment.
Step 2: Press: Ctrl+v and select the lines you want to comment:
Step 3: Shift- I #space (Enter Insert-at-left mode, type chars to insert. The selection will disappear, but all lines within it will be modified after Step 4.)
Step 4: Esc
单向手动
:set number
:10,12s/^/#
You could add the following mapping to your .vimrc
vnoremap <silent> # :s/^/#/<cr>:noh<cr>
vnoremap <silent> -# :s/^#//<cr>:noh<cr>
Highlight your block with:
Shift+v
# to comment your lines from the first column.
-# to uncomment the same way.
