python子进程

Question

我通常在Linux(手动)中执行Fortran文件:

1. 连接到服务器
2. 转到特定文件夹
3. ifort xxx.for -o xxx && ./xxx (其中'xxx.for'是我的Fortran文件,'xxx'是Fortran可执行文件)

但我需要从python(我是初学者)调用我的fortran文件(xxx.for),所以我使用subprocess以下命令:

cmd = ["ssh", sshConnect, "cd %s;"%(workDir), Fortrancmd %s jobname "%s -o  %s" exeFilename "%s && %s ./ %s%s"%(exeFilename)]

但我得到一个错误,我不确定是什么问题.这是完整的代码:

import string
import subprocess as subProc
from subprocess import Popen as ProcOpen
from subprocess import PIPE
import numpy
import subprocess

userID = "pear"
serverName = "say4"
workDir = "/home/pear/2/W/fortran/"
Fortrancmd = "ifort"
jobname = "rad.for"
exeFilename = "rad"

sshConnect=userID+"@"+servername

cmd=["ssh", sshConnect, "cd %s;"%(workDir), Fortrancmd %s jobname "%s -o  %s" exeFilename "%s && %s ./ %s%s"%(exeFilename)]

**#command to execute fortran files in Linux
**#ifort <filename>.for -o <filename> && ./<filename> (press enter)

**#example:ifort xxx.for -o xxx && ./xxx (press enter)

print cmd

如何编写一个执行上述所有3个步骤的python程序并避免我得到的错误？

你必须使用Python吗？
