Hello Ankur, you can use sleep() method to pause a text execution in webdriver. Python provides sleep() method which take seconds as an input and allows you to halt the execution for a specific duration of time. You can use it this way:
from selenium import webdriver
from time import sleep
driver = webdriver.Firefox(executable_path=r"D:\geckodriver.exe")
driver.implicitly_wait(2)
driver.maximize_window()
driver.get("http://gmail.com/")
sleep(5) #pauses the execution for 5 seconds
element = driver.find_element_by_id('email')
element.sendKeys('abc.def')
sleep(3) #pauses the execution for 3 seconds
driver.find_element_by_id('pass').send_keys('test123')
