webdriver - selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element:

Question

I'm trying to automatically generate lots of users on the webpage kahoot.it using selenium to make them appear in front of the class, however, I get this error message when trying to access the inputSession item (where you write the gameID to enter the game)

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.kahoot.it")

gameID = driver.find_element_by_id("inputSession")
username = driver.find_element_by_id("username")

gameID.send_keys("53384")

This is the error:

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element:
{"method":"id","selector":"inputSession"}

Answer 1

Looks like it takes time to load the webpage, and hence the detection of webelement wasn't happening. You can either use @shri's code above or just add these two statements just below the code driver = webdriver.Firefox():

driver.maximize_window() # For maximizing window
driver.implicitly_wait(20) # gives an implicit wait for 20 seconds
