在vim上運行python

Question

在askubuntu.com上我被告知如何run python on Vim。我正在測試可以在using python to solve a non linear equation處使用代碼第1或第2代碼python代碼的設置。

我唯一做的不同是在最後一行添加了print（a）。我昨天從外殼跑出來，它運行得很好。有人能告訴我發生了什麼問題嗎？

好了，所以我糾正與適當的問號vimrc的，

chmod +x ~/path/to/file/hw6problem2.py 

然後從VIM我跑

:Shell ./# 

，但我又收到了同樣的語法錯誤。 （是否有文件被保存爲.SH，因爲我不能得到任何.py文件來運行？）

dustin@dustin:~$ vim /home/dustin/Documents/School/UVM/Engineering/OrbitalMechanics/hw6problem2.py 

File "hw6problem2.py", line 14 
a0 = max(s/2, (s - c)/2)

這很可能是一個Python的問題。

另一方面，執行腳本和將輸出重定向到vim緩衝區（分割窗口）有很好的shell函數。

語法執行當前腳本（你應該使用chmod + x和家當線）：

:Shell ./# 

爲了增加功能，將它添加到.vimrc：

command! -complete=shellcmd -nargs=+ Shell call s:RunShellCommand(<q-args>) 

function! s:RunShellCommand(cmdline) 
    let isfirst = 1 
    let words = [] 
    for word in split(a:cmdline) 
    if isfirst 
     let isfirst = 0 " don't change first word (shell command) 
    else 
     if word[0] =~ '\v[%#<]' 
     let word = expand(word) 
     endif 
     let word = shellescape(word, 1) 
    endif 
    call add(words, word) 
    endfor 
    let expanded_cmdline = join(words) 
    rightbelow new 
    setlocal buftype=nofile bufhidden=wipe nobuflisted noswapfile nowrap 
    call setline(1, 'You entered: ' . a:cmdline) 
    call setline(2, 'Expanded to: ' . expanded_cmdline) 
    call append(line('$'), substitute(getline(2), '.', '=', 'g')) 
    silent execute '$read !'. expanded_cmdline 
    1 
endfunction
