            ## PyNASCAR

###### This is obviously not associated with NASCAR and is an unofficial project

## Overview

`pynascar` is a Python package for nascar race data acquisition and hopefully analysis

## Installation

Install via pip

```bash
pip install pynascar
```

updates will be made regularly until all public API endpoints are hit


## Quickstart

You can use this package to obtain data from the schedule or from any existing or live race including lap times, pit stop laps and times, all in race flags and all race control messages.

```python
from pynascar import Schedule, Race, set_options, get_settings
from pynascar.driver import DriversData

# Enable local caching for faster repeated runs
set_options(cache_enabled=True, cache_dir=".cache/", df_format="parquet")

# Series: 1=Cup, 2=Xfinity, 3=Trucks
year = 2025
series_id = 1
race_id = 5543

# Schedules
schedule = Schedule(year, series_id)
schedule.data.head()

# Race data (use reload=True to force network fetch even if cached)
race = Race(year, series_id, race_id, reload=True)
race.telemetry.lap_times.head()
race.telemetry.pit_stops.head()
race.events.head()

# Driver season aggregates
dd = DriversData.build(2025, 1, use_cache_only=False)
summary = dd.to_dataframe()
summary.sort_values("season_avg_position").head()
```

## Available Classes

Ill replace this with proper documentation if anyone cares. Just leave an issue.
