Yes. If you want runtime validation of data you’re taking in people recommended pydantic. If you’re looking for runtime validation within your own code I’ve seen people use beartype, though to be honest I don’t personally understand the value added from it
On one hand, I feel like I've been in a coma since covid because I've just been coasting along with Marshmallow and jsonschema, but on the other hand it's like a lot of the major advances have been in the past couple years. Apparently pydantic got a big version update in 2023? And now all these competing static type checkers?
msgspec must be insanely fast then: https://jcristharif.com/msgspec/benchmarks.html
But of course unless parsing and manipulating JSON is your bottleneck, Pydantic is great, too.
...or Marshmallow, which allows one to do many complex validations in a relatively trivial manner.
