[Tutor] os.popen - using commands and input %

[Vusa Moyo]

SOLVED> the code I used was.

for i in range(len(pids)):
    final.append(subprocess.Popen(["sudo pmap -d %s | grep private |awk
'{print $1}' | awk -FK '{print $1}'" % pids[i]], shell=True,
stderr=subprocess.PIPE, stdout=subprocess.PIPE).communicate()[0])

Allowed me to append the subprocess output to my list.

Thanks for the help everyone :-)
