Threading and Selenium - selenium

Question

I'm trying to make multiple tabs in Selenium and open a page on each tab simultaneously. Here is the code.
CHROME_DRIVER_PATH = "C:/chromedriver.exe"
from selenium import webdriver
import threading
driver = webdriver.Chrome(CHROME_DRIVER_PATH)
links = ["https://www.google.com/",
"https://stackoverflow.com/",
"https://www.reddit.com/",
"https://edition.cnn.com/"]
def open_page(url, tab_index):
driver.switch_to_window(handles[tab_index])
driver.get(url)
return
# open a blank tab for every link in the list
for link in range(len(links)-1 ): # 1 less because first tab is already opened
driver.execute_script("window.open();")
handles = driver.window_handles # get handles
all_threads = []
for i in range(0, len(links)):
current_thread = threading.Thread(target=open_page, args=(links[i], i,))
all_threads.append(current_thread)
current_thread.start()
for thr in all_threads:
thr.join()
Execution goes without errors, and from what I understand this should logically work correctly. But, the effect of the program is not as I imagined. It only opens one page at a time, sometimes it doesn't even switch the tab... Is there a problem that I'm not aware of in my code or threading doesn't work with Selenium?

Answer 1

There is no need in switching to new window to get URL, you can try below to open each URL in new tab one by one:
links = ["https://www.google.com/",
"https://stackoverflow.com/",
"https://www.reddit.com/",
"https://edition.cnn.com/"]
# Open all URLs in new tabs
for link in links:
driver.execute_script("window.open('{}');".format(link))
# Closing main (empty) tab
driver.close()
Now you can handle (if you want) all the windows from driver.window_handles as usual
