Invent your own comprehensions in Python

Python doesn't have tuple, frozenset, or Counter comprehensions, but you can invent your own by passing a generator expression to any iterable-accepting callable.

Avoiding empty strings in non-nullable Django string-based model fields

Django allows empty strings ('') even on non-nullable string fields, so you must explicitly enforce non-empty values using validation or database constraints rather than relying on null=False. The post argues for treating empty strings as invalid at the model or DB level (e.g., validators or CHECK constraints) to ensure true “required” semantics for string fields.

Stop Passing Primitives Everywhere (Use Value Objects)

By replacing primitives with immutable Value Objects, you can centralize validation and eliminate domain ambiguity for types like prices and percentages. This pattern ensures that invalid states are impossible to represent, creating a self-documenting and more reliable codebase without the overhead of heavy frameworks.
