Design-by-contract in Python3 with informative violation messages and inheritance (by Parquery)
contracts
PyContracts is a Python package that allows to declare constraints on function parameters and return values. Contracts can be specified using Python3 annotations, or inside a docstring. PyContracts supports a basic type system, variables binding, arithmetic constraints, and has several specialized contracts and an extension API. (by AndreaCensi)

Show HN: A design-by-contract Python package in ~100 lines
Seems you refer to a domain specific language in the annotations. This is exactly what https://github.com/AndreaCensi/contracts does (it's an amazing project but has a very large code base). However, I wanted to achieve something similar in pure python and as compact as possible – so there are compromises (like no real symbolic calculus)
What are some alternatives?
