我試圖從網站上提取一些資料，但是當代碼中給出的類名明顯有一個元素時，下面的代碼只會回傳一個空串列。
from selenium import webdriver
from selenium.webdriver.common.by import By
driver = webdriver.Chrome()
driver.get("https://terraria.fandom.com/wiki/Weapons")
search = driver.find_elements(By.CLASS_NAME, "infocard clearfix terraria compact")
print(search)
我真的很困惑，我什至嘗試使用 sleep 來給網站加載時間，但這并不影響結果。任何幫助都感激不盡。
