Selenium in Python: Nosuchelementexception: Message: No Such Element: Unable to Locate Element

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

Could be a race condition where the find element is executing before it is present on the page. Take a look at the wait timeout documentation. Here is an example from the docs

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

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )
finally:
    driver.quit()

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {method:css selector,selector:.ui flu~}

As per the HTML:

To identify the clickable element with text as Create download package you can use either of the following Locator Strategies:

• Using xpath:

  b = dr.find_element(By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")
  

Ideally to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

• Using XPATH:

  b = WebDriverWait(dr, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")))
  

• 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

To expand the Scotch Whisky menu you don't need to click on the item, instead you can simply Mouse Hover and grab a screenshot of the webpage using either of the following Locator Strategies:

• Using CSS_SELECTOR:

  driver.get('https://www.thewhiskyexchange.com/')
  ActionChains(driver).move_to_element(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a[title='Scotch Whisky']")))).perform()
  driver.save_screenshot('./Scotch_Whisky.png')
  driver.quit()
  

• Using XPATH:

  driver.get('https://www.thewhiskyexchange.com/')
  ActionChains(driver).move_to_element(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@title='Scotch Whisky']")))).perform()
  driver.save_screenshot('./Scotch_Whisky.png')
  driver.quit()
  

• Note : You have to add the following imports :

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

The username and password fields are within an frame, so you have to:

• Induce WebDriverWait for the desired frame to be available and switch to it.
• Induce WebDriverWait for the desired element to be clickable.

• You can use the following solution:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.common.by import By
  
  driver = webdriver.Firefox(executable_path=r'C:\\Utility\\BrowserDrivers\\geckodriver.exe')
  driver.get("http://sugang.korea.ac.kr")
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,"firstF")))
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.input_login[name='id']"))).send_keys('abc')
  driver.find_element_by_css_selector("input.input_login[name='pw']").send_keys("cdef")
