Python OpenCV Screen capture PID

Question

How to capture screen in opencv with pid number in python? So far, only these are what I found. def ara(): it was connected to a combobox in a different class, I added it to the code to add details. can this be done in python, or am I rowing in vain, I've been trying to do this for the last 1 week.

import numpy as np
import win32gui, win32ui, win32con
from threading import Thread, Lock
def ara(self):
    liste = []
    def winEnumHandler(hwnd, ctx):  #açık pencere isimlerini listeler
        if win32gui.IsWindowVisible(hwnd):
            if win32gui.GetWindowText(hwnd) == "":
                return
            liste.append(win32gui.GetWindowText(hwnd))
            self.windowName.config(values=(liste))
    win32gui.EnumWindows(winEnumHandler, None)

class ekranYakala:
    def __init__(self, window_name=None):
        # create a thread lock object
        self.lock = Lock()

        # find the handle for the window we want to capture.
        # if no window name is given, capture the entire screen
        if window_name is None:
            self.hwnd = win32gui.GetDesktopWindow()
        else:
            self.hwnd = win32gui.FindWindow(None, window_name)
            if not self.hwnd:
                raise Exception('Window not found: {}'.format(window_name))

        # get the window size
        window_rect = win32gui.GetWindowRect(self.hwnd)
        self.w = window_rect[2] - window_rect[0]
        self.h = window_rect[3] - window_rect[1]

        # account for the window border and titlebar and cut them off
        # border_pixels = 8
        # titlebar_pixels = 30
        # self.w = self.w - (border_pixels * 2)
        border_pixels = 1
        titlebar_pixels = 10
        self.w = self.w - border_pixels
        self.h = self.h - titlebar_pixels - border_pixels
        self.cropped_x = border_pixels
        self.cropped_y = titlebar_pixels

        # set the cropped coordinates offset so we can translate screenshot
        # images into actual screen positions
        self.offset_x = window_rect[0] + self.cropped_x
        self.offset_y = window_rect[1] + self.cropped_y
    def get_screenshot(self):
        # get the window image data
        wDC = win32gui.GetWindowDC(self.hwnd)
        dcObj = win32ui.CreateDCFromHandle(wDC)
        cDC = dcObj.CreateCompatibleDC()
        dataBitMap = win32ui.CreateBitmap()
        dataBitMap.CreateCompatibleBitmap(dcObj, self.w, self.h)
        cDC.SelectObject(dataBitMap)
        cDC.BitBlt((0, 0), (self.w, self.h), dcObj, (self.cropped_x, self.cropped_y), win32con.SRCCOPY)
        signedIntsArray = dataBitMap.GetBitmapBits(True)
        img = np.fromstring(signedIntsArray, dtype='uint8')
        img.shape = (self.h, self.w, 4)
        dcObj.DeleteDC()
        cDC.DeleteDC()
        win32gui.ReleaseDC(self.hwnd, wDC)
        win32gui.DeleteObject(dataBitMap.GetHandle())
        img = img[...,:3]
        img = np.ascontiguousarray(img)
        return img

    def get_screen_position(self, pos):
        return (pos[0] + self.offset_x, pos[1] + self.offset_y)

But I want to do this with the pid number, I want to capture two screens with the same name.
