The `MetaData` class in Python SQLAlchemy is a container that provides a way to store, organize, and manage database schema information. It acts as a catalog that holds references to various database tables, columns, constraints, and other schema elements. With `MetaData`, developers can define and manage the structure of a database using Python code. It allows for convenient creation, modification, and deletion of database objects through a unified API. Additionally, `MetaData` can be used to generate SQL statements and perform operations like introspection and synchronization between the code and the actual database schema.
