Selenium/Python: no such element with: driver.find_element(By.ID)

Question

I try to locate elements on a website which are in a form to then send keys to login but I get an error, see below:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="username"]"}

Line of code is:

driver.find_element(By.ID, "username").send_keys("test123")

For HTML code see:

HTML code

I use latest version of Python/Selenium and PyCharm.

I hope someone can help.

Answer 1

I don't see anything wrong in that line of code. Try one of the below

• Try applying implicit wait as below:

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(20)

• Check if there is a frame/ iframe covering this element, if yes, try below code before locating the element

iframe = driver.find_element_by_xpath("<XPath expression of the frame>")
driver.switch_to.frame(iframe)

To switch back to the main DOM:

driver.switch_to.default_content()

• If the frame doesn't exist, then try inducing explicit wait as below:

element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "username"))

Below imports you will require:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

Answer 2

Given the HTML:

the element is a <input> element which would accept text input using send_keys() method.

Solution

Ideally to send a character sequence to an <input> element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:

• Using CSS_SELECTOR:

  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.input#username[name='username']"))).send_keys("Coding_89")
  

• Using XPATH:

  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='input' and @id='username'][@name='username']"))).send_keys("Coding_89")
  

• Note: You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
