Learn Python for Bioinformatics
Read DNA, align sequences, and call variants, one function at a time. Built for biologists and bioinformatics students. You write real Python, run it in the browser, and watch it pass. No installs, no toy apps, no lectures.
11 projects, 275 hands-on levels, first project free.
Problems you will solve
- reverse-complement a DNA strand
- translate a gene to a protein
- align two sequences
By the end you can process real sequence data yourself.
What you will build
- Foundations: code through bioinformatics
- DNA Basics
- Transcription & Translation
- Sequence Composition & Motifs
- Pairwise Alignment
- Mutations & Variants
- FASTA & FASTQ Parsing
- Phylogenetics
- Population Genetics
- Genome Search & Assembly
- Capstone: Characterize an Unknown Sample

Frequently asked questions
Do I need to know how to code to start Bioinformatics?
No. The Bioinformatics with Python track starts from the fundamentals and builds up, and the first project is free.
Do I need to install anything?
No. Every level runs in your browser and is graded the moment your code works. No Python install, no setup.
What language will I write?
Python. You write real Python, run it, and get instant feedback across 275 hands-on levels.
Is it free to start?
Yes. The first project is free with no card. Unlimited access to all 33 tracks is $12 a month or $100 a year.
