Fill username and password using selenium in python

Docs: https://selenium-python.readthedocs.io/navigating.html

For versions 4.3.0 (released in June 2022) and later, calls to find_element_by_* and find_elements_by_* were removed from Selenium. You need to use the new API:

from selenium.webdriver.common.by import By

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()

# To catch <input type="text" id="passwd" />
password = driver.find_element(By.ID, "passwd")
# To catch <input type="text" name="passwd" />
password = driver.find_element(By.NAME, "passwd")

password.send_keys("Pa55worD")

driver.find_element(By.NAME, "submit").click()

The original response, for API versions 4.2.0 or previous:

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()

username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")

username.send_keys("YourUsername")
password.send_keys("Pa55worD")

driver.find_element_by_name("submit").click()

A note to your code: Select() is used to act on a Select Element (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select).
