Markov: Build a Text Generator
Feed it a book and it writes new sentences in the same voice. You build the great-grandparent of every language model, in about fifteen lines.
What you'll be able to build
Feed it a book and it writes new sentences in the same voice. You build the great-grandparent of every language model, in about fifteen lines. Along the way you pick up real, transferable Python skills, not just this one project:
- building a transition model with dict.setdefault
- zip & pairwise iteration
- seeding RNG for reproducibility
- random.choice & weighted sampling
- training-then-generating workflow
- list accumulation & join
A course like this one
Yours is built from your own placement, so module count and depth will differ. This map shows what a advanced-level Python learner building Markov actually gets.
- Module 1: Idiomatic Python and comprehensions5 lessons
Builds the production-ready version of the script for your markov.
- Module 2: Profiling and performance5 lessons
Builds the production-ready version of the reusable module for your markov.
- Module 3: Concurrency, async, and I/O5 lessons
Builds the production-ready version of the service boundary for your markov.
- Module 4: Data structures and algorithms5 lessons
Builds the production-ready version of the data flow workflow for your markov.
- Module 5: Iterators and advanced control flow5 lessons
Builds the production-ready version of the function that powers your markov.
- Module 6: Typing and production hardening3 lessons
Builds the production-ready version of the release package for your markov.
How the lessons actually work
Every lesson has you predict what a piece of Python code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Markov, and a runnable proof page tied to your own code.
Common questions
How long does the Markov: Build a Text Generator course take?
about 7 hours, across 6 modules and 28 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.
Do I need experience?
Yes. This is an advanced-tier Python project, so it assumes you're already comfortable writing and reading Python before you start.
How much does it cost?
$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.
