# ladybug

Ladybug is a Python library to analyze, modify, and visualize EnergyPlus Weather files (epw). You can download epw files from [EPWMap](http://www.ladybug.tools/epwmap/).

This repository is the core library that is the base for the Ladybug Grasshopper Plugin. For plugin-specific questions and comments refer to [ladybug-grasshopper](https://github.com/ladybug-tools/ladybug-grasshopper).

## Note

For the Legacy Ladybug Grasshopper Plugin see [this repository](https://github.com/ladybug-tools/ladybug-legacy).

## [API Documentation](https://www.ladybug.tools/ladybug/docs/)

## Installation

`pip install ladybug-core`

## Usage

```python
# load epw weather data
from ladybug.epw import EPW
epw_data = EPW('path_to_epw_file')
dry_bulb_temp = epw_data.dry_bulb_temperature

# Get altitude and longitude
from ladybug.location import Location
from ladybug.sunpath import Sunpath

# Create location. You can also extract location data from an epw file.
sydney = Location('Sydney', 'AUS', latitude=-33.87, longitude=151.22, time_zone=10)

# Initiate sunpath
sp = Sunpath.from_location(sydney)
sun = sp.calculate_sun(month=11, day=15, hour=11.0)

print('altitude: {}, azimuth: {}'.format(sun.altitude, sun.azimuth))
>>> altitude: 72.26, azimuth: 32.37
```
