from Pybites Podcast · host Julian Sequeira & Bob Belderbos
This week we talk about code smells. 💡Code smells are characteristics in the code that might indicate deeper issues or potential problems. While they're not necessarily bugs, they can be a sign of poor code quality or maintainability issues. 😱We distilled 15 common smells ranging from generic programming to Python specific issues. We hope it will make your more conscious of your code as well as code you'll review. 🐍 💪If you have any feedback, hit us up on:- LinkedIn- X- Email(Also for any podcast topic requests ...)Mentioned Dictionary Dispatch Pattern videoAnd to write cleaner, more maintainable code, in the context of (complex) real world applications, check out our 1:1 coaching options.Chapters:00:00 Intro music00:20 What are code smells?01:11 1.
