在 vim 上运行 python

Question

在 askubuntu.com 上，有人告诉我如何使用 run python on Vim。我正在测试与using python to solve a non linear equation 的代码 1st 或 2nd 代码 python 代码一起使用的设置。

我唯一不同的是添加了 print(a) 作为最后一行。我昨天从 shell 运行了这个，它运行良好。有人可以告诉我出了什么问题吗？

好的，所以我用适当的问号更正了 vimrc，

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

然后我从 vim 跑了

:Shell ./#

但我再次收到相同的语法错误。 （文件是否必须保存为 .sh，因为我无法运行任何 .py 文件？）

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

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

这很可能是 python 问题。

另一方面，有一个很棒的 shell 函数用于执行脚本并将输出重定向到 vim 缓冲区（拆分窗口）。

执行当前脚本的语法（你应该有 chmod +x 和 shebang 行）：

:Shell ./#

要添加功能，请将其添加到.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
