Become smarter about Python
Get a short, actionable Python tip each day. Tips are short (under 100 words), actionable (you can apply them right away) and they're also sent as a flashcard, ideal if you're a visual learner.
Become smarter about Python ππ§
What readers have to say
The diagrams are always so well done they don't even need supporting text.
I always recommend Rodrigo's posts to friends and colleagues.
Newcomers will learn Python concepts in an engaging way, and experienced programmers can refresh their knowledge and even learn something new about latest Python releases.
Thanks Rodrigo!
This is a great daily read regardless of your Python level. Within a minute or two; you are introduced to a language component or mechanism, a common use case for it, and example code demonstrating it.
Quality and fun. Highly recommended!
Rodrigo, your "tip cards" have been smashing, elegant and informative! Thank you for sharing them!
I really enjoy your Python drops! So much new exposure to what's possible with the language!
Love the short to the point code snippets. Then you really bring it home with graphics. Just awesome.
Very interesting, looks like every time I read your posts I learn something new!
