使用regexp提取网址的主机部分的最佳方法是什么？

(?:https?:\/\/)?(?:[^@\n]+@)?(?:www\.)?([^:\/\n?]+)

import re

url = "https://www.example.com/some/path?query=string"
pattern = r'(?:https?:\/\/)?(?:[^@\n]+@)?(?:www\.)?([^:\/\n?]+)'
match = re.search(pattern, url)

if match:
    host = match.group(1)
    print(host)  # 输出：example.com
else:
    print("No match found")
