I love requests+lxml, use it fairly regularly, just a few quick notes:

1. lxml is way faster than BeautifulSoup - this may not matter if all you're waiting for is the network. But if you're parsing something on disk, this may be significant.

2. Don't forget to check the status code of r (r.status_code or less generally r.ok)

3. Those with a background in coding might prefer the .cssselect method available in whatever object the parsed document results in. That's obviously a tad slower than find/findall/xpath, but it's oftentimes too convenient to pass upon.

4. Kind of automatic, but I'll say it anyway - scraping is a gray area, always make sure that what you're doing is legitimate.
