"""Prediction module for weather and photovoltaic forecasts.

This module provides a `Prediction` class to manage and update a sequence of
prediction providers. The `Prediction` class is a subclass of `PredictionContainer`
and is initialized with a set of forecast providers, such as `WeatherBrightSky`,
`WeatherClearOutside`, and `PVForecastAkkudoktor`.

Usage:
    Instantiate the `Prediction` class with the required providers, maintaining
    the necessary order. Then call the `update` method to refresh forecasts from
    all providers in sequence.

Example:
    # Create singleton prediction instance with prediction providers
    from akkudoktoreos.prediction.prediction import prediction

    prediction.update_data()
    print("Prediction:", prediction)

Classes:
    Prediction: Manages a list of forecast providers to fetch and update predictions.

Attributes:
    pvforecast_akkudoktor (PVForecastAkkudoktor): Forecast provider for photovoltaic data.
    weather_brightsky (WeatherBrightSky): Weather forecast provider using BrightSky.
    weather_clearoutside (WeatherClearOutside): Weather forecast provider using ClearOutside.
