As in @Eugenij's answer, you can use individual process objects to get their CPU usage. — CoderCharmander

You can use psutil library for your task

pip install psutil

Usage:

import psutil

chrome = None
for proc in psutil.process_iter():
    if proc.name() == "chrome.exe":
        chrome = proc
        print(chrome.cpu_percent())

@Burak Try to set interval: print(chrome.cpu_percent(interval=0.1))

You can use this code:

import psutil

for proc in psutil.process_iter():
    if proc.name() == 'chrome.exe':
        try:
            pinfo = proc.as_dict(attrs=['pid'])
        except psutil.NoSuchProcess:
            pass
        else:
            print(pinfo['pid'])
            p = psutil.Process(pinfo['pid'])
            print(p.cpu_percent(1))

But you should count sum of this process
