Brian #1: 6 ways to improve the architecture of your Python project (using import-linter) Piglei Using import-linter to define architectural layers check to make sure imports don’t violate (import from upper layers) can also check for more contracts, such as forbidden - disallow a specific from/to import independence - list of modules that shouldn’t import from each other Fixing violations a process introduced to set exceptions for each violation in a config file then fix violations 1 at a time (nice approach) use the whole team if you can Common methods for fixing dependency issues Merging and splitting modules Dependency Injection, including using protocols to keep type hints without the need to import just for types Use simpler dependency types Delaying function implementations module global methods set by caller, or adding a simple plugin/callback system Configuration driven Setting import statements in a config file and using import_string() at runtime Replace function calls with event-driven approaches Michael #2: Mountaineer Mountaineer is a batteries-included web framework for Python and React. Mountaineer focuses on developer productivity above all else, with production speed a close second. 📝 Typehints up and down the stack: frontend, backend, and database 🎙️ Trivially easy client[HTML_REMOVED]server communication, data binding, and function calling 🌎 Optimized server rendering for better accessibility and SEO 🏹 Static analysis of web pages for strong validation: link validity, data access, etc. 🤩 Skip the API or Node.js server just to serve frontend clients Brian #3: Why Python's Integer Division Floors Guido van Rossum
