How to get list of PID for all the running process with python code?

Question

I am working on a project which needs the list of PID of all the running process. I want it via python programming language. How to get it? Thanks in adv.

@AkshayNevrekar, Yes it solves partially my problem but this solution seems specific to windows OS. I want generic solution. Thanks. — , Jan 31 '19 at 14:43

If you are on Linux just use subprocess.Popen to spawn the ps - ef command, and then fetch the second column from it. Below is the example.

import subprocess as sb

proc_list = sb.Popen("ps -ef | awk '{print $2} ' ", stdout=sb.PIPE).communicate()[0].splitlines()

for pid in proc_list:
    print(pid)

If you want to keep it platform independent use psutil.pids() and then iterate over the pids. You can read more about it here, it has bunch of examples which demonstrates what you are probably trying to achieve.

Hope this helps.

Please execuse any typo if any, i am just posting this from mobile device.

If you want a dictionary with pid and process name, you could use the following code:

import psutil

dict_pids = {
    p.info["pid"]: p.info["name"]
    for p in psutil.process_iter(attrs=["pid", "name"])
}

Please consider upvoting and accepting the answer if it helped you. — Rohit, Jan 31 '19 at 18:42
