I 开发者_C百科run it in a batch file

The subprocess module is now preferred over os.system(). A simple example, assuming run_prog.bat contains the command you need:

import subprocess
cmd = "run_prog.bat"
proc = subprocess.Popen(cmd)

You can use the os module:

import os
os.system('mybatchfile.bat')

or use the subprocess module
