Python dictionary construction from process list

Hi,

This is out of my expertise but i wanted to shared it anyways. One colleague wanted to help him with the creation of a pair key:value from one command that lists the processes, in python. With a little bit of testing i came to the following form:


import os
import subprocess
from subprocess import Popen, PIPE
username = subprocess.Popen(['/bin/ps','-eo','pid,uname'], stdout=PIPE, stderr=PIPE)
firstlist = username.stdout.read().split('\n')
dict = {}
for str in firstlist:
  if (str != ''):
    secondlist = str.split()
    key = secondlist[0]
    value = secondlist[1]
    dict[key]=value
print(dict)

Now, i think there are better ways to write this but it works also in this way.
If you find better ways, please leave a message 🙂

Cheers
