selenium.common.exceptions.WebDriverException: Message: ‘geckodriver’ executable needs to be in PATH with GeckoDriver Selenium Firefox

The error says it all :

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH. 

Which implies that GeckoDriver binary is not in the Classpath

While working with Selenium v3.x you have to download the latest GeckoDriver from this url and store it in your system and mention the absolute path while initiating the webdriver and Web Browser session as follows :

from selenium import webdriver

driver = webdriver.Firefox(executable_path="C:\\path\\to\\geckodriver.exe")
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()
