selenium. Working with tabs in Python?

Question

Python

Good people, don't judge cruelly, I'm just learning, despair has come and I really hope for your help, I can't learn how to switch between windows on selemiun (python).
Here is my code, the task is simple in two pages to log in to social networks:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys


class Bot:
  def __init__(self):
    self.driver = webdriver.Firefox()
    self.authorization_vk()
    self.authorization_fb()
    

  def authorization_vk(self): #АВТОРИЗАЦИЯ VK:

    
    self.driver.get('https://vk.com')
    self.driver.find_element_by_xpath('//*[@id="index_email"]').send_keys("email")
    self.driver.find_element_by_xpath('//*[@id="index_pass"]').send_keys("pass")
    self.driver.find_element_by_xpath('//*[@id="index_login_button"]').click()

    
  def authorization_fb(self): #АВТОРИЗАЦИЯ fb:

    self.driver.execute_script("window.open('https://www.facebook.com','_blank');") # Интуитивно вставила так ссылку и она хотя бы заработала, возможно есть другие варианты...
    self.driver.switch_to_window(driver.window_handles[1]) #Пробовала вычислять окна и вставлять номер id конкретного окна, что-то мелькало на экране, но результата не дало.
    self.driver.find_element_by_xpath('//*[@id="email"]').send_keys("email")
    self.driver.find_element_by_xpath('//*[@id="pass"]').send_keys("pass")
    self.driver.find_element_by_xpath('//*[@id="u_0_2"]').click()
    

    
def main():
  b = Bot()
  
  
if __name__ == '__main__':
  main()

For some reason, switch_to_window is the only working option in my case, I would gladly use element.send_keys(Keys.CONTROL + 't'), but it doesn't want to work with me...
