使用if-else语句的Selenium不起作用

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

# 启动浏览器
driver = webdriver.Chrome()
driver.get("http://example.com")

try:
    # 等待元素加载
    wait = WebDriverWait(driver, 10)
    element = wait.until(EC.presence_of_element_located((By.ID, "element_id")))

    # 使用if-else语句判断元素是否显示
    if element.is_displayed():
        print("Element is displayed")
    else:
        print("Element is not displayed")
except Exception as e:
    print(f"An error occurred: {e}")
finally:
    # 关闭浏览器
    driver.quit()
