Learn Python,
one small win at a time.
A school-style curriculum that starts at print("Hello") and ends with classes, recursion and ciphers. Every lesson is a short read, a three-question quiz, and real Python you run and auto-grade right here in the browser.

How a lesson works
Read the short version
Each lesson opens with a plain-language article: what the idea is, and the code that shows it. No wall of text.
Answer 3 quick questions
A three-question quiz with real explanations, so you find the gap before it becomes a habit.
Write code that gets graded
Your Python runs right in the browser and an autograder checks the result, so you always know it works.

Stories about women in tech, AI, and the road into a first developer job.
LearningLearning to code at 30: what actually worked
Tutorials feel productive and teach very little. Here is the routine that turned a stalled year of "learning to code" into actually shipping things.
AIAI is rewriting entry-level tech work. Here is what to do about it
The tasks that used to be a first job — boilerplate, small fixes, tidy-up work — are exactly what AI is best at. That changes the entry point, not the destination.
Women in TechThe first programmers were women. And the industry forgot.
Ada Lovelace wrote the first algorithm, six women programmed the ENIAC, and Grace Hopper taught machines to understand English. Then the job got famous — and the women quietly disappeared from the story.
