pyvoteview 0.2.1

PyVoteview package to process VoteView site data.

PyVoteview

PyVoteview is a Python package for programmatically accessing and analyzing U.S. Congressional voting records from Voteview. It provides a simple interface to retrieve, filter, and process roll call data for both the House and Senate across sessions and years.

Features

• Fetch voting records by Congress number or year
• Retrieve data for a range of sessions or years
• Fast, parallelized data loading using Polars and ThreadPoolExecutor

Installation

PyVoteview requires Python 3.11+ and Polars:

pip install pyvoteview

Quick Start

from pyvoteview.core import get_records_by_congress, get_records_by_year

# Get House voting records for the 117th Congress
df = get_records_by_congress(117, "House")

# Get Senate voting records for the year 2020
df = get_records_by_year(2020, "Senate")

# Get records for a range of sessions
df_range = get_records_by_congress_range(115, 117, "House")

All functions return a Polars DataFrame.
