ROSALIND is a "platform for learning bioinformatics through problem solving".
I'll update this file as we go along.
Within each directory, you should find a <file>.py that contains the code I used.
Concernig the BioPtyhon, all classes, objects and so on can be found here. A tutorial/documentation is also available.
I use a Conda environment when I run scripts containing BioPython module.
source activate biopython where biopython is a Conda environment.
