使用python selenium选择隐藏的<li> </ li>

我有源代码html代码：

<li><a href="javascript:void(0);"  onclick="set_timezone('+3');"><span>+3</span>Moscow, Riyadh</a></li>
<li><a href="javascript:void(0);" onclick="set_timezone('+4');"><span>+4</span>Muscat</a>     </li>

print ('Opening browser...')
driver = webdriver.Firefox(executable_path = 'C:geckodrivergeckodriver.exe')
driver.get("https://www.betexplorer.com/next/soccer/")
search_timezone =
driver.find_element_by_xpath("//ul[@class='timezone__list']")
driver.execute_script('arguments[0].setAttribute("onclick", "set_timezone(+3);")', search_timezone)
什么也没发生。

我也尝试过：

driver = webdriver.Firefox(executable_path = 'C:geckodrivergeckodriver.exe')
driver.get("https://www.betexplorer.com/next/soccer/")
search_timezone =
driver.find_element_by_xpath("//ul[@class='timezone__list']")
wait = WebDriverWait(driver, 10)
action = ActionChains(driver)
action.move_to_element(search_timezone).perform()
select_timezone = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "+3 Moscow, Riyadh")))
select_timezone.click()
