How to implement the same two browser instances all the time and put different links in each?

Question

I have this example of code:

import concurrent.futures    
from concurrent.futures import ThreadPoolExecutor
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

links = ['https://en.wikipedia.org/wiki/File:Mechanitis_Polymnia_Chrysalis.jpg',
    'https://en.wikipedia.org/wiki/File:William_Cornwallis_as_Admiral_(cropped).jpg',
    'https://en.wikipedia.org/wiki/File:Battle_of_Saint_Charles.jpg',
    'https://en.wikipedia.org/wiki/File:Stephen_Curry_Shooting_(cropped)_(cropped).jpg']

def open(url):
    chromeOptions = webdriver.ChromeOptions()
    driver = webdriver.Chrome(options=chromeOptions)
    driver.get(url)
    print('+')

with concurrent.futures.ThreadPoolExecutor(max_workers=2) as ex:
    for link in links:
        ex.submit(open, link)

Everything works well, and different links are pasted into each browser, which is what I want. But each time, new browser windows are created.

Answer 1

I modified your code a little using the same driver instead of opening a new one and it's working

from concurrent.futures import ThreadPoolExecutor
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

links = ['https://en.wikipedia.org/wiki/File:Mechanitis_Polymnia_Chrysalis.jpg',
         'https://en.wikipedia.org/wiki/File:William_Cornwallis_as_Admiral_(cropped).jpg',
         'https://en.wikipedia.org/wiki/File:Battle_of_Saint_Charles.jpg',
         'https://en.wikipedia.org/wiki/File:Stephen_Curry_Shooting_(cropped)_(cropped).jpg']


def open(url, index):
    drivers[index].execute_script(f"window.open('{url}','_self')")
    print('+')


NB_WINDOWS = 2
chromeOptions = webdriver.ChromeOptions()
drivers = []
for i in range(NB_WINDOWS):
    drivers.append(webdriver.Chrome(options=chromeOptions))

print("Drivers : ", len(drivers))

with ThreadPoolExecutor(max_workers=2) as ex:
    i = 0
    for link in links:
        ex.submit(open, link, i % NB_WINDOWS)
        i = i+1
