promptdojo vs real python
real python is the deepest, most respected python writing on the web. but the depth lives behind a $19/mo membership, and the format is long-form articles, not runnable code. promptdojo is built around the opposite trade-offs: every step is a runnable cell, the first three chapters are free with no signup, and the lessons are organized around how ai writes python wrong — not around python's reference manual.
you write python with cursor or claude open. you need a fast feedback loop to test what ai wrote, not a 4000-word essay on iteration protocols. you want to start in the browser today, no signup.
you want the encyclopedia. you read long-form, you take notes, and you're happy to pay $19/mo for the depth. you don't mind that almost every premium article is text + screenshots, not runnable.
