Python 3.7 will ship with a new module called "dataclasses", which has been defined in PEP 557.
- What is this module?
- What are the problems that PEP 557 authors try to solve?
- What was the chosen design, and why?
- How does it compare against the tools that already exist?
This talk will deeply cover "dataclasses", but also "attrs", "box", "thingy", and others.
