a library for scraping things
scrapelib is a library for making requests to less-than-reliable websites, it is implemented (as of 0.7) as a wrapper around requests.
scrapelib originated as part of the Open States project to scrape the websites of all 50 state legislatures and as a result was therefore designed with features desirable when dealing with sites that have intermittent errors or require rate-limiting.
Advantages of using scrapelib over alternatives like httplib2 simply using requests as-is:
- All of the power of the suberb requests library.
- HTTP, HTTPS, and FTP requests via an identical API
- support for simple caching with pluggable cache backends
- request throttling
- configurable retries for non-permanent site failures

- python 2.7, >=3.3
- requests >= 2.0 (earlier versions may work but aren’t tested)
import scrapelib s = scrapelib.Scraper(requests_per_minute=10) # Grab Google front page s.get('http://google.com') # Will be throttled to 10 HTTP requests per minute while True: s.get('http://example.com')
