Selenium Python Code

webd = webdriver.Chrome(service=s, options=options)
webd.get("url")
webd.find_element(By.XPATH, "//div[@class='w-100']//div[@class='ma3']//section//div[@class='mv4']")

Is it the correct way to fetch

>Solution :

You can try something like contains() method:

webd.find_element(By.XPATH, "//*[contains(@class,'w-100')]/div/section/div[@class='mv4']")
