Independently observed

SQLAlchemy

Leader

SQLAlchemy provides Python developers with a toolkit for working with SQL databases, featuring both a low-level SQL expression language and an optional object mapper. It balances flexibility and abstraction, allowing developers to write type-safe database queries while retaining the ability to use hand-optimized SQL when needed.
