我是python的新手，我在数组中有url列表，并且是迭代列表，但我遇到了错误

for index,value in enumerate(lists):
    urllib.request.urlopen(value)

Answer 1

Checking您提供的URL的 HTTP状态代码，我得到：

Response: 404 Not Found for your URL https://i.ytimg.com/vi/y4vD9LM2z3k/hqdefault_live.jpg。

因此，您的第三个链接不起作用，当请求使用urllib打开它时，它将返回404错误。另外两个链接有效，您没有问题，仅使用它们时程序也不应该返回任何错误。

P.S .：为什么可以使用enumerate？

for link in lists: 
    urllib.request.urlopen(link)
