A clean, async-focused Python3 API for IQVIA data

🌻 pyiqvia: A clean, async-focused Python3 API for IQVIA™

pyiqvia is an async-focused Python3 library for allergen, asthma, and disease data from the IQVIA™ family of websites (such as https://pollen.com, https://flustar.com, and more).

Python Versions

pyiqvia is currently supported on:

• Python 3.8
• Python 3.9
• Python 3.10

Installation

pip install pyiqvia

Usage

import asyncio

from aiohttp import ClientSession

from pyiqvia import Client


async def main() -> None:
    """Run!"""
    # Note that ZIP codes must be provided as strings:
    client = Client("80012")

    # Get current allergen information:
    await client.allergens.current()

    # Get more information on the current allergen outlook:
    await client.allergens.outlook()

    # Get extended forecast allergen information:
    await client.allergens.extended()

    # Get historic allergen information:
    await client.allergens.historic()

    # Get current asthma information:
    await client.asthma.current()

    # Get extended forecast asthma information:
    await client.asthma.extended()

    # Get historic asthma information:
    await client.asthma.historic()

    # Get current cold and flu information:
    await client.disease.current()

    # Get extended forecast cold and flu information:
    await client.disease.extended()

    # Get historic cold and flu information:
    await client.disease.historic()


asyncio.run(main())

Retries

By default, pyiqvia will retry appropriate errors 4 times (with an exponentially increasing delay in-between). This logic can be changed by passing a different value for request_retries to the Client constructor:

import asyncio

from pyiqvia import Client


async def main():
    client = Client("80012", request_retries=5)

    # ...


asyncio.run(main())

Connection Pooling

By default, the library creates a new connection to IQVIA with each coroutine. If you are calling a large number of coroutines (or merely want to squeeze out every second of runtime savings possible), an aiohttp ClientSession can be used for connection pooling:

import asyncio

from aiohttp import ClientSession

from pyiqvia import Client


async def main() -> None:
    """Run!"""
    async with ClientSession() as session:
        client = Client("80012", session=session)

        # ...


asyncio.run(main())
