Executing a DOS program from within Python

[iapain]

Use os.system and if you wanna get rid of console window use subprocess
as gary said, you could have better options like killing proc if it
hang/stuck using win32api (if you are using windows) else process
timeout.

ret = os.system('sample.exe') # ret will have return code and os.system
execute sample.exe

#using subprocess

import subprocess
process = subprocess.Popen('sample.exe', stdout=subprocess.PIPE)
#you can print error/output using stderr/stdout pipe

Both are easy to implement!
Thanks!!
