popen.kill not closing browser window

Question

I have spent the past few days trying to automate the process of flattening a PDF and this function is the one I have found works best. The only issue is that the a.kill() command is not being read, resulting in the browser remaining open after the function is complete. How can I close the browser window after the save process is finished?

import time
import subprocess
import keyboard

def chrome():
    test = "test"
    name = "file:///C://Users//akcgo//Documents//CARB//ARBER//PDFS//Company A.pdf"
    a = subprocess.Popen("C://Program Files (x86)//Google//Chrome//Application//chrome.exe")
    time.sleep(1)
    keyboard.write(name)
    time.sleep(1)
    keyboard.press_and_release('enter')
    time.sleep(1)
    keyboard.press_and_release(['ctrl', 'p'])
    time.sleep(1)
    keyboard.press_and_release('enter')
    time.sleep(1)
    keyboard.write(test)
    time.sleep(.5)
    keyboard.press_and_release('enter')
    time.sleep(2)
    a.kill()
    # keyboard.press_and_release(['ctrl', 'w']) doesn't work either

You could get the subprocess' PID by using pid = a.pid, then calling os.kill(pid, signal.SIGTERM) or os.kill(pid, signal.SIGKILL).
