`pyiqvia` is an async-focused Python3 library for allergen, asthma, and disease data from
the [IQVIA™][iqvia] family of websites (such as [Pollen.com][pollen],
[FluStar][flustar], and more).

# Python Versions

`pyiqvia` is currently supported on:

- Python 3.10
- Python 3.11
- Python 3.12

# Installation

```bash
pip install pyiqvia
```

# Usage

```python
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:

```python
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`][aiohttp] `ClientSession` can be used for
connection pooling:

```python
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())
```
