Preface
Welcome to Starting Out with Python, Second Edition. This book uses the Python language
to teach programming concepts and problem-solving skills, without assuming any previous
programming experience. With easy-to-understand examples, pseudocode, flowcharts, and
other tools, the student learns how to design the logic of programs and then implement
those programs using Python. This book is ideal for an introductory programming course
or a programming logic and design course using Python as the language.

As with all the books in the Starting Out With series, the hallmark of this text is its clear,
friendly, and easy-to-understand writing. In addition, it is rich in example programs that
are concise and practical. The programs in this book include short examples that highlight
specific programming topics, as well as more involved examples that focus on problem
solving. Each chapter provides one or more case studies that provide step-by-step analysis
of a specific problem and shows the student how to solve it.

Control Structures First, Then Classes
Python is a fully object-oriented programming language, but students do not have to understand
object-oriented concepts to start programming in Python. This text first introduces the student
to the fundamentals of data storage, input and output, control structures, functions, sequences
and lists, file I/O, and objects that are created from standard library classes. Then the student
learns to write classes, explores the topics of inheritance and polymorphism, and learns to write
recursive functions. Finally, the student learns to develop simple event-driven GUI applications.
