Roboworld

roboworld is an educational Python package designed for students to learn basic programming concepts, such as,

variables,
function calls,
conditionals,
loops and
recursion.

Students must navigate Robo (a robot) through different two-dimensional discrete worlds. Robo represents a very simplistic machine that can only deal with elementary instructions, i.e., method calls. Therefore, students have to extend the missing functionality step by step. Through this process they learn

to divide a problem into smaller pieces,
to abstract,
to recognize patterns, and
to design and implement algorithms.

roboworld is heavily inspired by Kara. You can install the package via pip:

pip install roboworld
