schema

https://github.com/keleshev/schema a library for validating python data structures by schema definitions, gave me a wow moment. (i have a slightly less original one here: https://github.com/MoserMichael/kwchecker )

If you haven't seen, these alternatives might also be helpful: * https://github.com/keleshev/schema * https://github.com/alecthomas/voluptuous * https://github.com/Pylons/colander

That's rather verbose, though. I prefer the much more functional "schema" library: https://github.com/keleshev/schema

I am using https://github.com/keleshev/schema with python. I see a solid need for a schema here and there but don't buy into the whole heavy handed XSD. (Who hasn't struggled with the completely broken Microsoft .NET SOAP schema). From a practical perspective I am tending to validate multiple sections of json with a schema closer to the code that uses it. This way I don't have to maintain some massive schema at the top. (It is great for decorators @validate_body(Schema({'size': Use(int), 'name': unicode}) def handler(body): aa = body['size'] ...

I had come across another schema validation lib for Python on Github a while back (but never tried/used it): https://github.com/halst/schema

The examples grandparent posted of great code (not sure why they deleted, it was a great comment!): https://github.com/alecthomas/voluptuous https://github.com/halst/schema
