scrapelib is a library for making requests to less-than-reliable websites.
Source: https://github.com/jamesturk/scrapelib
Documentation: https://jamesturk.github.io/scrapelib/

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 using requests as-is:
- HTTP(S) and FTP requests via an identical API
- support for simple caching with pluggable cache backends
- highly-configurable request throtting
- configurable retries for non-permanent site failures
- All of the power of the suberb requests library.
scrapelib is on PyPI, and can be installed via any standard package management tool:
poetry add scrapelib
or:
pip install scrapelib
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')
