generators

Raymond Hettinger explains Python's dataclasses module, showing the problem it solves and its key design decisions. He places it in a progression from tuples and dicts through named tuples and attrs.

James Powell's nearly two-hour PyData talk builds up Python's data model, decorators, generators and context managers, coding live in Vim. It aims to take intermediate programmers toward real Python expertise.

Max Brunsfeld introduces Tree-sitter, a parsing system for developer tools that offers incremental parsing and robust error recovery through a uniform C API. The talk explains the design, based on LR extended to GLR parsing.
