如何在数组中循环url并在驱动程序Python Selenium中打印css选择器元素

Question

想要找到每个产品的销售数量(数组中给定的URL(使用硒web驱动程序

这是我的代码

urls=["https://shopee.com.my/Pantene-Shampoo-750ml-i.52968176.7669592698/","https://shopee.com.my/PureMAE-Ylang-Ylang-and-Grapefruit-Shampoo-250ML-i.238433989.4820842024/","https://shopee.com.my/Some-By-Mi-Cica-Peptide-Anti-Hair-Loss-Shampoo-285ml-Tonic-150ml-Treatment-50ml-i.18874494.3274522052/","https://shopee.com.my/-JULYME-Anti-Hair-Loss-Perfume-Hair-Shampoo-500ml-i.219158269.6815232839/"]
for url in urls:
driver.get(url)
print(driver.find_element_by_css_selector('div.aca9MM').text)

预期结果是：

3.4k135.3k1.9k

但是我在第5行出错了并且只能打印出第一个3.4k

urls=["https://shopee.com.my/Pantene-Shampoo-750ml-i.52968176.7669592698/","https://shopee.com.my/PureMAE-Ylang-Ylang-and-Grapefruit-Shampoo-250ML-i.238433989.4820842024/","https://shopee.com.my/-JULYME-Anti-Hair-Loss-Perfume-Hair-Shampoo-500ml-i.219158269.6815232839/"]
driver = webdriver.Chrome('/Users/YOURNAME/Desktop/chromedriver')
#for every url in the list of urls
try:
for url in urls:
driver.get(url)
print(driver.find_element_by_css_selector('div.aca9MM').text)
except:
print("error")    

3.4k
13
error

您提供的第三个URL上似乎没有div.aca9MM。
