How can I use Python's urllib for advanced web scraping?

You can use Python's urllib to handle URL requests, parse responses, and manage cookies. What specific features are you interested in?

I want to handle redirects and manage cookies effectively.

To handle redirects, you can use urllib.request.urlopen() which follows redirects by default. For cookies, consider using http.cookiejar to manage them.

Can you show me a code example for managing cookies?

Sure! Here's a simple example:

import urllib.request
import http.cookiejar

# Create a cookie jar to hold cookies
cj = http.cookiejar.CookieJar()

# Create an opener that uses the cookie jar
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))

# Use the opener to fetch a URL
response = opener.open('http://example.com')
print(response.read())
