I noticed this issue only after running a linter. Sometimes we’re not familiar with the tricky edge cases or conventions of a particular language. A convenient way to catch and fix such issues — including formatting, styling, and even some security problems — is to use linters. For example, you can use golangci-lint for Go, ESLint for JavaScript, and Pylint for Python. In fact, almost every widely used programming language has its own linter or code quality tool. Linters are especially helpful when generating code with AI — they help keep your code clean and safe, at least to some degree.

pytype is based in part upon byterun https://github.com/google/pytype/blob/main/docs/developers/i...
I learnt a lot about bytecode interpreters from working on it, and it helped me understand the cpython source code a lot more easily from having played with a python translation of it first.

Flake8
flake8 is a python tool that glues together pycodestyle, pyflakes, mccabe, and third-party plugins to check the style and quality of some python code.
Flake8: This tool checks for style errors and simple programming mistakes.
