Peewee
Peewee is a lightweight, expressive Object-Relational Mapper (ORM) library for Python that simplifies database interactions by allowing developers to work with database records as Python objects. It supports SQLite, MySQL, PostgreSQL, and CockroachDB, offering features like query building, transactions, and migrations through a simple, intuitive API. Designed for small to medium-sized projects, it emphasizes ease of use and minimal boilerplate code.
Developers should learn Peewee when building Python applications that require database persistence but want to avoid the complexity of larger ORMs like SQLAlchemy, especially for prototypes, small web apps, or scripts where simplicity and quick setup are priorities. It's ideal for use cases such as data analysis tools, simple CRUD applications, or educational projects where a straightforward database layer is needed without sacrificing expressiveness.
