"""
Calculate the Precision for a single query.
Args:
model_output (List[Dict[str, Any]]): The list of retrieved documents from the model.
Each dictionary contains:
- 'source': A unique identifier for the document.
- 'score': The relevance score of the document.
contexts (List[Dict[str, Any]]): A list of dictionaries representing the relevant contexts.
Each dictionary contains:
- 'source': A unique identifier for the relevant document.
Returns:
float: The Precision score for the given query.
Precision measures the proportion of retrieved documents that are relevant.
