Scraper and utilities for UK Parliamentary bills
Project description
ParlPy
Package to scrape and process UK Parliamentary bills, votes and MP contact information.
Written as part of University of Bath Integrated Project module.
Usage
Install
pipenv install ParlPy=0.1.0
Example Usage
To fetch bills updated since our scraper was last called (uses pickled variable for persistence between program runs)
from parlpy.bills.bill_list_fetcher import BillsOverview
test_fetcher = BillsOverview()
test_fetcher.get_changed_bills_in_session(session="All")
print(test_fetcher.bills_overview_data)
... script can stop and be rerun later, next time bills_overview_data will contain fewer items, unless reset_datetime_last_scraped() has been called first
To fetch all bills in session and print them:
from parlpy.bills.bill_list_fetcher import BillsOverview
test_fetcher2 = BillsOverview()
test_fetcher2.update_all_bills_in_session()
print(test_fetcher2.bills_overview_data)
