The textbook is meant as a first programming course and is tightly aligned with the University of Otago introductory programming course called Practical Programming (http:// www.cs. otago.ac. nz/student/ papers. php?name= COMP150).

This textbook is a modified version of "How to Think Like a Computer Scientist: Learning with Python 2nd Edition", by Jeffrey Elkner, Allen B. Downey and Chris Meyers (http:// www.openbookpro ject.net/ thinkcs/ python/ english2e/).
