python subprocess

import os

os.system('etc/program') #full path of the program

os.system('gedit')

#os.system('notpad.exe') #for windows

 

or:

os.popen()

 

os.popen() behaves similar to a file open(), the default is "r" for read, so for write to have to addd a "w". You can specify the buffer size in bytes or use the default of zero.

 

os.popen('program').write('whatever')

 

a = os.popen("cmd","w")

a.write("bla")

*******************

Use another method, subprocess, which is recommended. http://docs.python.org/library/subprocess.html

import subprocess# Command with shell expansion
subprocess.call('ls -l $HOME', shell=True)

subprocess.Popen('echo "Hello world!"', shell=True) #command through the shell.
