How could I find the location of a running process using Python

Question

I need to find the location of the web-browser in the program I'm making.

I've decided to do this by running a browser window then finding the path of it. I've looked at psutil but still can't figure out how to do it.

I'm doing this cause I can't seem to open a new window using the webbrowser library, it opens in a new tab regardless of wherever I tell it to or not. So I plan to use the commands explained here: http://kb.mozillazine.org/Command_line_arguments#List_of_command_line_arguments_.28incomplete.29

I'm using Python 3.8.6 on Windows 10

Answer 1

Found a solution using psutil finally!

import psutil

def findPath(name):
    for pid in psutil.pids():
        if psutil.Process(pid).name() == name:
            return psutil.Process(pid).exe()

print(findPath('firefox.exe'))

This loops through all pids and checks to see if the pids name is the same as the name variable passed to the findPath function.

Link to original code (psutil)

I modified original code to meet your needs. Unfortunately I cannot test them since I am on Android platform and psutil module in Termux's Python can't access (since Android update) stats due security/privacy reasons so if they don't work please tell me

Simple approach

import psutil

def findPath(name: str) -> list:
    ls: list = [] # since many processes can have same name it's better to make list of them
    for p in psutil.process_iter(['name', 'pid']):
        if p.info['name'] == name:
            ls.append(psutil.Process(p.info['pid']).exe())
    return ls

More advanced

import os
import psutil

def findPathAdvanced(name: str) -> list:
    ls: list = [] # same reason as previous code
    for p in psutil.process_iter(["name", "exe", "cmdline", "pid"]):
        if name == p.info['name'] or p.info['exe'] and os.path.basename(p.info['exe']) == name or p.info['cmdline'] and p.info['cmdline'][0] == name:
            ls.append(psutil.Process(p.info['pid']).exe())
    return ls
