如何使用Python运行输入文件的可执行文件？

I am running an executable from cmd:

我从cmd运行可执行文件:

*.exe input.inp

I want to run it using python and tried following:

我想使用python运行它并尝试以下:

os.system('"*.exe"')

But don't know how to specify input file as well. Any suggestions?

但是不知道如何指定输入文件。有什么建议?

2 个解决方案

#1

import os
from subprocess import Popen, PIPE

p = Popen('fortranExecutable', stdin=PIPE) #NOTE: no shell=True here
p.communicate(os.linesep.join(["input 1", "input 2"]))

#2

I had to launch cmd window and specify input file location from within Python script. This page was really helpful in getting it done.

我必须启动cmd窗口并在Python脚本中指定输入文件位置。这个页面非常有助于完成它。

I used Popen(['cmd', '/K', 'command']) from above page and replaced '/K' with '/C' in it to run and close the cmd window.

我在上面的页面中使用了Popen(['cmd','/ K','command'])并将'/ K'替换为'/ C'来运行并关闭cmd窗口。
