我一直在尝试使用Python和Selenium从某个网站上刮一些价格我写的脚本看起来工作得很好，但有时我会在代码的这一部分得到一个错误：

#Select "Date de début"
    select = Select(driver.find_element("xpath",'//*[@id="startDateSet"]'))
    options = select.options
    option = options[i]
    select.select_by_visible_text(option.text)
    print (option.text)
    ListDateEfPrincipal3Semaines.append(option.text)

Error
我不明白为什么有时会发生这种情况，通常它应该只得到选项列表（其中包含至少10个元素，然后提取这些信息，但在这里似乎返回的列表只包含1个元素。
下面是前面提到的Select类：Select Class Image
下面是完整的代码：

print ("\nDébut du Programme EF Principal pour 3 semaines !")
ListPriceEfPrincipal3Semaines = []
ListDateEfPrincipal3Semaines = []
for i in range(1, 10):
    print("\n")
    #add options to the Chrome tab
    options = webdriver.ChromeOptions()
    options.add_argument("--start-maximized")
    driver = webdriver.Chrome(executable_path=path, options=options)
    driver.implicitly_wait(10) #wait max 5 seconds for the cookie page to appear, if it finds it sooner it continues
    
    driver.get('https://www.ef.fr/ils/book-now/')
    driver.find_element("xpath",'//*[@id="onetrust-accept-btn-handler"]').click()

    select.select_by_visible_text('3 Semaines')

    #Select "Date de début"

    print(FinalPrice)

    driver.close()

    print(FinalPrice)
    ListPriceEfEstival3Semaines.append(FinalPrice)
    driver.close()

print ("\nFin du Programme EF estival pour 3 semaines !\n")

这是我得到的结果
