Get process CPU usage in percentage in python-CodePudding

I'm making an destktop application like task manager. How to get the specific cpu usage of google.exe?

CodePudding user response：

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())

CodePudding user response：

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
