Running command lines in python

I'm having troubles running commands lines in python. I'm currently using 

os.system("cd " + path)
os.system(command)

However, os.system opens a new console each time.

What class should i use for it to work ? How can I intercept the output ?

Thanks !

I always use os.chdir("dirname") This function can work just like the cd function, so you can do both os.chdir("dir_thats_right_here") and os.chdir("/dir/thats/far/away")

To fix the above:

os.chdir(path)
os.system(command)

To capture data I would look into subprocess: http://docs.python.org/2/library/subprocess.html

Since you are using python 1.7:

output=os.popen(command,"r").readlines()

from subprocess import call
call(["ls", "-l"])

The advantage of subprocess versus system is that it is more flexible. You can get the stdout, stderr, the "real" status code, better error handling, etc.

Also, check out the Python docs.
