在python中运行特定的批处理命令

Question

What if I want to include a single batch command that isn't already in a file in python?

for instance:

REN *.TXT *.BAT

Could I put that in a python file somehow?

Answer 1

The "old school" answer was to use os.system . I'm not familiar with Windows but something like that would do the trick:

import os
os.system('ren *.txt *.bat')

Or (maybe)

import os
os.system('cmd /c ren *.txt *.bat')

---

But now, as noticed by Ashwini Chaudhary, the "recommended" replacement for os.system is subprocess.call

If REN is a Windows shell internal command:

import subprocess
subprocess.call('ren *.txt *.bat', shell=True)

If it is an external command:

import subprocess
subprocess.call('ren *.txt *.bat')

Answer 2

try this:

cmd /c ren *.txt *.bat

or

cmd /c "ren *.txt *.bat"

Answer 3

示例使用子进程从Python执行Linux命令：

mime = subprocess.Popen("/usr/bin/file -i " + sys.argv[1], shell=True, stdout=subprocess.PIPE).communicate()[0]

Answer 4

I created a test.py containing this, and it worked....

from subprocess import Popen    # now we can reference Popen
process = Popen(['cmd.exe','/c ren *.txt *.tx2'])
