<h3 id="the-strange-history-of-think-python">The strange history of
“Think Python”</h3>
<p>(Allen B. Downey)</p>
<p>In January 1999 I was preparing to teach an introductory programming
class in Java. I had taught it three times and I was getting frustrated.
The failure rate in the class was too high and, even for students who
succeeded, the overall level of achievement was too low.</p>
<p>One of the problems I saw was the books. They were too big, with too
much unnecessary detail about Java, and not enough high-level guidance
about how to program. And they all suffered from the trap door effect:
they would start out easy, proceed gradually, and then somewhere around
Chapter 5 the bottom would fall out. The students would get too much new
material, too fast, and I would spend the rest of the semester picking
up the pieces.</p>
<p>Two weeks before the first day of classes, I decided to write my own
book. My goals were:</p>
<ul>
<li><p>Keep it short. It is better for students to read 10 pages than
not read 50 pages.</p></li>
<li><p>Be careful with vocabulary. I tried to minimize the jargon and
define each term at first use.</p></li>
<li><p>Build gradually. To avoid trap doors, I took the most difficult
topics and split them into a series of small steps.</p></li>
<li><p>Focus on programming, not the programming language. I included
the minimum useful subset of Java and left out the rest.</p></li>
</ul>
<p>I needed a title, so on a whim I chose <em>How to Think Like a
Computer Scientist</em>.</p>
<p>My first version was rough, but it worked. Students did the reading,
and they understood enough that I could spend class time on the hard
topics, the interesting topics and (most important) letting the students
practice.</p>
<p>I released the book under the GNU Free Documentation License, which
allows users to copy, modify, and distribute the book.</p>
<p> </p>
<p>What happened next is the cool part. Jeff Elkner, a high school
teacher in Virginia, adopted my book and translated it into Python. He
sent me a copy of his translation, and I had the unusual experience of
learning Python by reading my own book.</p>
<p>Jeff and I revised the book, incorporated a case study by Chris
Meyers, and in 2001 we released <em>How to Think Like a Computer
Scientist: Learning with Python</em>, also under the GNU Free
Documentation License. As Green Tea Press, I published the book and
started selling hard copies through Amazon.com and college book stores.
Other books from Green Tea Press are available at <a
href="greenteapress.com">greenteapress.com</a>.</p>
<p>In 2003 I started teaching at Olin College and I got to teach Python
for the first time. The contrast with Java was striking. Students
struggled less, learned more, worked on more interesting projects, and
generally had a lot more fun.</p>
<p>Over the last five years I have continued to develop the book,
correcting errors, improving some of the examples and adding material,
especially exercises. In 2008 I started work on a major revision—at the
same time, I was contacted by an editor at Cambridge University Press
who was interested in publishing the next edition. Good timing!</p>
<p>I hope you enjoy working with this book, and that it helps you learn
to program and think, at least a little bit, like a computer
scientist.</p>
<h3 id="acknowledgements-for-think-python">Acknowledgements for “Think
Python”</h3>
<p>(Allen B. Downey)</p>
<p>First and most importantly, I thank Jeff Elkner, who translated my
Java book into Python, which got this project started and introduced me
to what has turned out to be my favorite language.</p>
<p>I also thank Chris Meyers, who contributed several sections to
<em>How to Think Like a Computer Scientist</em>.</p>
<p>And I thank the Free Software Foundation for developing the GNU Free
Documentation License, which helped make my collaboration with Jeff and
Chris possible.</p>
<p> </p>
<p>I also thank the editors at Lulu who worked on <em>How to Think Like
a Computer Scientist</em>.</p>
<p>I thank all the students who worked with earlier versions of this
book and all the contributors (listed in an Appendix) who sent in
corrections and suggestions.</p>
<p>And I thank my wife, Lisa, for her work on this book, and Green Tea
Press, and everything else, too.</p>
