marshmallow
A lightweight library for converting complex objects to and from simple Python datatypes.
Somehow get a serializer going for your database models. I used marshmallow and flask-marshmallow

I use Pandera, so I just need to define the expected input/output schemas (i.e. column names, types, and constraints on them), and Pandera automatically generates fake data for the unit tests, and validates the result: https://github.com/unionai-oss/pandera

webargs
A friendly library for parsing HTTP request arguments, with built-in support for popular web frameworks, including Flask, Django, Bottle, Tornado, Pyramid, webapp2, Falcon, and aiohttp.

Mergify
Updating dependencies is time-consuming.. Solutions like Dependabot or Renovate update but don't merge dependencies. You need to do it manually while it could be fully automated! Add a Merge Queue to your workflow and stop caring about PR management & merging. Try Mergify for free.

msgspec
A fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML
Full support for validation and serialisation of attrs classes and msgspec Structs. Where previously only Pydantic models and types where supported, you can now mix and match any of these three libraries. In addition to this, adding support for another modelling library has been greatly simplified with the new plugin architecture

Project mention: What features would you want in a new programming language? | /r/ProgrammingLanguages | 2023-01-03I started using a design by contract library for a Python project this year and it made my code safer and easier to use.

Hi, depending on what kind of programming you do (i.e. use lots of type annotation) I'd recommend either Pydantic or Marshmallow. First comes usually paired with FastAPI, but both do a phantastic job. There's also an extension for Flask + Marshmallow as well for Flask + Pydantic. Personally I see Pydantic as the more modern one.
