The article discusses the performance implications of using generators vs list comprehensions when joining strings with str.join() in Python. Contrary to expectations, using a generator expression with str.join() is slower than a list comprehension because the CPython implementation converts the generator to a list internally before joining the strings, negating the memory efficiency ben...

Ruff: Internals of a Rust-backed Python linter-formatter - Part 1
Ruff is an extremely fast Python linter written in Rust, deriving its speed from parsing Python code and implementing linting rules natively in Rust rather than Python. The article provides insights into Ruff's internals, including its initial implementation using RustPython's parser, the evolution to a hand-written recursive descent parser, and its caching and parallelization mechanisms.
