[問題] 用python執行接參數的執行檔

[Holocaust123 (Terry)]

  (OS是XP，Python版本2.6.4)

  我想用Python執行某個exe檔

  該exe檔後面接一個參數

  並希望Python跑完script後馬上關閉

  而不要等到exe結束才關閉

  script如下：

      import os
      exe   = r'C:\Program Files\hfs\hfs.exe'
      param = r'C:\Program Files\hfs\hfs.vfs'
      os.spawnl(os.P_NOWAIT, exe, param)

  執行該script後hfs.exe的確有被執行

  但沒吃到hfs.vfs這個參數...

  (我直接把 hfs.vfs 拖曳到 hfs.exe 的圖示上是可以正常執行的)

  請問我哪邊弄錯了？

  謝謝

推 danqing:加個引號?
  請問你是說這樣嗎：

  import os
  exe   = r'"C:\Program Files\hfs\hfs.exe"'
  param = r'"C:\Program Files\hfs\hfs.vfs"'
  os.spawnl(os.P_NOWAIT, exe, param)

  出現錯誤耶QQ

  Traceback (most recent call last):
  File "C:\Program Files\hfs\run.py", line 4, in <module>
    os.spawnl(os.P_NOWAIT, exe, param)
  File "C:\Program Files\Python26\lib\os.py", line 612, in spawnl
    return spawnv(mode, file, args)
  OSError: [Errno 22] Invalid argument

推 qwerasdft:"Program Files" 這個呢?
→ Holocaust123:param = r'C:\"Program Files"\hfs\hfs.vfs'這樣的話
→ Holocaust123:產生一樣的錯誤
推 ibmibmibm:param要是list吧：['param1','param2','param3']之類的
→ Holocaust123:spawnv(mode,path,args)的args才是list/tuple的樣子.
推 doghib:用subprocess.Popen([exe, ])
  thx 成功了

  參考 Python v2.6.4 documentation 的 18.1.3.4 (Replacing the os.spawn family)

  P_NOWAIT example:

  pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg")

  ==> pid = Popen(["/bin/mycmd", "myarg"]).pid

  ...(下略)

  import subprocess
  exe   = r'C:\Program Files\hfs\hfs.exe'
  param = r'C:\Program Files\hfs\hfs.vfs'
  subprocess.Popen([exe, param]).pid
