How to get vim using anaconda as default python3?

Question

I am using Manjaro/Arch Linux and I use vim from sudo pacman -S vim instead of build it from source

I want to run my .py files in vim by F5 but when I added these to ~/.vimrc:

map <F5> :call CompileRunGcc()<CR>
    func! CompileRunGcc()
        exec "w"
if &filetype == 'c'
            exec "!g++ % -o %<"
            exec "!time ./%<"
elseif &filetype == 'cpp'
            exec "!g++ % -o %<"
            exec "!time ./%<"
elseif &filetype == 'java'
            exec "!javac %"
            exec "!time java %<"
elseif &filetype == 'sh'
            :!time bash %
elseif &filetype == 'python'
            exec "!time python %"
elseif &filetype == 'html'
            exec "!firefox % &"
elseif &filetype == 'go'
    "        exec "!go build %<"
            exec "!time go run %"
elseif &filetype == 'mkd'
            exec "!~/.vim/markdown.pl % > %.html &"
            exec "!firefox %.html &"
endif
    endfunc

it will show (originally in Chinese)

function CompileRunGcc --> error
In line 1:
E382: cannot write in，has been set as 'buftype'
when running .py files

I am using anaconda as my default python environment, and I installed them at ~/.anaconda

Now this work but it will throw EOF Error when meeting input()

map <F5> :call RunPython()<CR>
function! RunPython()
    exec "w"
    if &filetype == 'python'
            if search("@profile")
                    exec "AsyncRun kernprof -l -v %"
                    exec "copen"
                    exec "wincmd p"
             elseif search("set_trace()")
                     exec "!python3 %"
             else
                    exec "AsyncRun -raw python3 %"
                    exec "copen"
                    exec "wincmd p"
            endif
    endif
endfunc
