jump to the next python class or function in vim

Question

I'm trying to jump to the next python class or function in vim with the following commands:

autocmd FileType python nnoremap <buffer> [[ ?^class|^\s*def<CR>
autocmd FileType python nnoremap <buffer> ]] /^class|^\s*def<CR>

But it doesn't work. Vim prompted:

Error detected while processing FileType Auto commands for "python":
E492: Not an editor command: ^\s*def<CR>

How to fix this?

Answer 1

After lots of trying, I found the following code worked. I need to add \\ before |

autocmd FileType python nnoremap <buffer> [[ ?^class\\|^\s*def<CR>
autocmd FileType python nnoremap <buffer> ]] /^class\\|^\s*def<CR>

As an alternative way, I found that putting the two lines in ~/.vim/ftplugin/python.vim is more convenient

nnoremap [[ ?^class\|^\s*def<CR>
nnoremap ]] /^class\|^\s*def<CR>
