what is DuckDBPyRelation from Python dict?

What is DuckDBPyRelation in Python, and how can I use it effectively to manage and query my data?

DuckDBPyRelation is a component of the DuckDB Python library. It allows users to create symbolic SQL queries that represent operations like filtering, joining, or aggregating data without executing them immediately. This means you can incrementally build and manipulate queries before running them to get the actual results.

You can construct a DuckDBPyRelation from various sources, such as SQL queries or data files like CSV, JSON, or Parquet. Once the relation is created, it can be used in further queries or operations, making it an effective tool for managing and querying data within Python scripts. The flexibility to convert query results into formats like Pandas DataFrames or Arrow Tables enhances its usability for data analysis tasks.

By using DuckDBPyRelation, you streamline the process of handling and analyzing data, ensuring efficient and effective data management in your Python projects.
