我有一个很艰难的时期我的包裹周围BeautifulSoup头。什么会有所帮助。感谢您的时间。

I am having a really hard time wrapping my head around BeautifulSoup. Anything would help. Thank you for your time.

推荐答案

但是，这完全是普通的Python。你得到一个列表，并希望每行输出它的网址。

But this is completely basic Python. You're getting a list, and you want to output it one URL per line.

for url in urls:
    print url
