| Summary: | "This text helps beginners develop their own Python programs. Experiments with fully completed programs are provided at the beginning of each chapter, allowing instructors to use the text in CS0 courses where students do not learn programming. Programming projects appear later in each chapter. Students are encouraged either to write the code that implements the functions introduced earlier or extend the existing programs. All the projects push students to explore further on their own".. |

EXPLORATIONS/IN COMPUTING
An Introduction to Computer Science
J
and Python Programming
Explorations in Computing: An Introduction to Computer Science and
Python Programming teaches you how to use programming skills to explore
fundamental concepts and computational approaches to solving problems.
It gives you an introduction to computer science concepts and computer
programming.
The text uses Python as the lab software so that you can seamlessly transition
from introductory projects to more advanced studies in later courses. It also
introduces Python programming, providing you with sufficient programming
skills so you can implement your own programs.
The interactive lab projects in each chapter allow you to examine important
ideas In computer science, particularly how algorithms offer computational
solutions to problems. You can type expressions, view results, and run experi-
ments that help you understand the concepts in a hands-on way. The Python
software modules for each lab project are available on the author’s website.
Features
• Emphasizes computational thinking and important concepts in computing
• Gives you sufficient Python programming skills
• Includes tutorial projects that encourage you to explore a particular
problem and solve it computationally
• Contains standard exercises that test your understanding of the topics
covered
• Provides the software and other ancillaries on the author’s website
