The main focus is on the Python language. First it discusses the problems of beginning programmers and discusses the existing solutions. The core of the work is to design and implement a new system that is able to automatically evaluate student solutions to specific Python programming tasks. The work shows the internal layout and operation, describes its inputs and outputs and demonstrates the possibilities of inclusion into the teaching. As a case study, the system was deployed to support the teaching of the subject Scripting Languages at the FIT VUT in Brno in the academic ...
