Introduction to Programming in Python

Description

The ideal beginner’s introduction to Python programming for both students and professionals

• A broad-based, applications-based approach: learn Python through examples from science, mathematics, engineering, and commercial computing
• No toy problems: teach yourself Python by solving important and interesting real-world problems
• Focuses on what matters most: the most useful and important Python language features
• Teaches through code tested for compatibility with Python 2.x and Python 3.x
• Includes question-and-answer sections, exercises, and creative exercises throughout
• From Robert Sedgewick and Kevin Wayne, co-authors of the global best-seller Algorithms

Introduction to Programming in Python: An Interdisciplinary Approach emphasizes interesting and important problems, not toy applications. The authors focus on Python’s most useful and significant features, rather than aiming for exhaustive coverage that bores novices. All of this book’s code has been crafted and tested for compatibility with both Python 2 and Python 3, making it relevant to every programmer and any course, now and for many years to come.

An extensive amount of supplementary information is available at introcs.cs.princeton.edu/python. With source code, I/O libraries, solutions to selected exercises, and much more, this companion website empowers people to use their own computers to teach and learn the material.

Today, anyone in a scientific or technical discipline needs programming skills. Python is an ideal first programming language, and Introduction to Programming in Python is the best guide to learning it.

Princeton University’s Robert Sedgewick, Kevin Wayne, and Robert Dondero have crafted an accessible, interdisciplinary introduction to programming in Python that emphasizes important and engaging applications, not toy problems. The authors supply the tools needed for students to learn that programming is a natural, satisfying, and creative experience.

This example-driven guide focuses on Python’s most useful features and brings programming to life for every student in the sciences, engineering, and computer science.

Coverage includes

• Basic elements of programming: variables, assignment statements, built-in data types, conditionals, loops, arrays, and I/O, including graphics and sound
• Functions, modules, and libraries: organizing programs into components that can be independently debugged, maintained, and reused
• Object-oriented programming and data abstraction: objects, modularity, encapsulation, and more
• Algorithms and data structures: sort/search algorithms, stacks, queues, and symbol tables
• Examples from applied math, physics, chemistry, biology, and computer science—all compatible with Python 2 and 3

Drawing on their extensive classroom experience, the authors provide Q&As, exercises, and opportunities for creative practice throughout. An extensive amount of supplementary information is available at introcs.cs.princeton.edu/python.
