Run multiple web browsers simultaneously Selenium Python 3

问题

I'm attempting to open multiple chrome drivers at once and have it run as fast as possible. It opens the first page, and it has to load completely before the second function executes with "browser_2".
Is there a way to make these functions load at the same time?

notice - I'm hiding "Proxy_list" from my post to protect those ips for this post.

browser_1 = 0
browser_2 = 1
browser_3 = 2
browser_4 = 3
browser_5 = 4
browser_6 = 5
browser_7 = 6
browser_8 = 7
browser_9 = 8
browser_10 = 9
Link_1 = "https://www.google.com"

session_list = [browser_1, browser_2, browser_3, browser_4, browser_5, browser_6, browser_7, browser_8, browser_9, browser_10]



def create_browser(browser):
    options = webdriver.ChromeOptions()
    options.add_argument('--proxy-server=%s' % (Proxy_list[browser]))
    options.add_argument("start-maximized")
    options.add_argument("disable-infobars")
    options.add_argument("--disable-extensions")
    print("opening session #" + str(browser+ 1))
    # Defines Browser
    browser = webdriver.Chrome(options=options)
    browser.get(Link_1)
    return browser


create_browser(browser_1)
create_browser(browser_2)
create_browser(browser_3)
create_browser(browser_4)
create_browser(browser_5)

Here is the sample code.

I have tried and it would open multiple browsers at same time.

from selenium import webdriver
from multiprocessing import Process, Pipe, Pool

def create_browser(num):
    options = webdriver.ChromeOptions()
    options.add_argument("start-maximized")
    options.add_argument("disable-infobars")
    options.add_argument("--disable-extensions")
    # Defines Browser
    browser = webdriver.Chrome(options=options)
    browser.get('https://mail.google.com/')

    return browser


pool = Pool(processes=10)  # Maximum number of browsers opened at same time

for i in range(0, 5):  # Five browsers will be created
    async_result = pool.apply_async(create_browser, args=(i))

pool.close()
pool.join()

---

Updated:

You can pass parameter like below.

def test_function(x, y, z=0):
    # do something

...

async_result = pool.apply_async(test_function, args=(1, 2), kwds={'z':3})  # x=1, y=2, z=3

---

In your case:

session_list = [browser_1, browser_2, browser_3, browser_4, browser_5, browser_6, browser_7, browser_8, browser_9, browser_10]

pool = Pool(processes=10)  # Maximum number of browsers opened at same time

for i in range(0, len(session_list)):  # Ten browsers will be created
    async_result = pool.apply_async(create_browser, args=(session_list[i]))

pool.close()
pool.join()
