Improve Your Python: Python Classes and Object Oriented Programming The class is a fundamental building block in Python. It is the underpinning for not only many popular programs and libraries, but the Python standard library as well. Understanding what classes are, when to use them, and how the can be useful is essential, and the goal of this article. In the process, we'll explore what the term Object-Oriented Programming means and how it ties together with Python classes. Everything Is An Object... How to Think Like a Computer Scientist — How to Think like a Computer Scientist: Interactive Edition Welcome! Take a tour, experiment with Python, join more than 850,000 other readers in learning how to think like a computer scientist with Python. import turtle import random def main(): tList = [] head = 0 numTurtles = 10 for i in range(numTurtles): nt = turtle.Turtle() # Make a new turtle, initialize values nt.setheading(head) nt.pensize(2) nt.color(random.randrange(256),random.randrange(256),random.randrange(256)) nt.speed(10) nt.tracer(30,0) tList.append(nt) # Add the new turtle to the list head = head + 360/numTurtles for i in range(100): moveTurtles(tList,15,i) w = tList[0] w.up() w.goto(-130,40) w.write("How to Think Like a ",True,"center","30px Arial") w.goto(-130,-35) w.write("Computer Scientist",True,"center","30px Arial") def moveTurtles(turtleList,dist,angle): for turtle in turtleList: # Make every turtle on the list do the same actions. turtle.forward(dist) turtle.right(angle) main() (welcome)

Stanford Portable Library for C++ This package contains the code for the Stanford Portable C++ library, as described in the paper by Eric Roberts and Keith Schwarz included in the doc directory. You can download the source code for the library by clicking on the following link: cpplib.zip. The Makefile in the root directory should make a complete version of the library on Unix-based systems or Mac OS X. Building the .lib file for Windows-based systems depends on what version of the operating system and what programming environment you are using. Python beginner's mistakes Every Python programmer had to learn the language at one time, and started out as a beginner. Beginners make mistakes. This article highlights a few common mistakes, including some I made myself. Beginner's mistakes are not Python's fault, nor the beginner's.

Face Recognition with Python, in under 25 lines of code - Real Python The following is a guest post by Shantnu Tiwari, who has worked in the low level/embedded domain for ten years. Shantnu suffered at the hands of C/C++ for several years before he discovered Python, and it felt like a breath of fresh air. He is now trying to share his love. In this post we’ll look at a surprisingly simple way to get started with face recognition using Python and the open source library OpenCV. Hands-On Python A Tutorial Introduction for Beginners Hands-On Python A Tutorial Introduction for Beginners Contents Chapter 1Beginning With Python 1.1. Trie This article is about a tree data structure. For the French commune, see Trie-sur-Baïse. A trie for keys "A","to", "tea", "ted", "ten", "i", "in", and "inn". In the example shown, keys are listed in the nodes and values below them. Each complete English word has an arbitrary integer value associated with it.

Python popularity over Ruby – Is it real or myth? Python and Ruby are two popular scripting languages that strongly support object oriented structure. Their implementation is quite different from existing languages like C and Java. The two languages are simpler to use and especially designed to make things faster for the programmers. How to make beautiful data visualizations in Python with matplotlib It’s been well over a year since I wrote my last tutorial, so I figure I’m overdue. This time, I’m going to focus on how you can make beautiful data visualizations in Python with matplotlib. There are already tons of tutorials on how to make basic plots in matplotlib. There’s even a huge example plot gallery right on the matplotlib web site, so I’m not going to bother covering the basics here. However, one aspect that’s missing in all of these tutorials and examples is how to make a nice-looking plot.

Where The Rants Go By Zed A. Shaw I've had it. M O R E W A R E . O R G I completed the CS50 - Introduction to Computer Sciences certification course at HarvardX offered by edX online teaching system. I found it really interesting, and decided to put some effort into it, trying to help the project leader, prof. David Malan, and the project Team in their wonderful work. PyGaze: An open source tool with fascinating research applications A few of weeks ago I got a email from a friend who was attending an education technology conference. In the note he referenced PyGaze, an open source project I might be interested in. I have a deep interest in educational psychology, and so I was fascinated by what I read about PyGaze—an open source toolbox for eye tracking in Python. The website told me that it runs on Linux, but I wanted to learn more about eye tracking and the role it plays in psychological research. I also wanted to know more about the project and how it is contributing to research and its implications for open source. In this interview, the lead developer for the project, Edwin Dalmaijer, who works at the University of Oxford's Department of Experimental Psychology doing research and programming, provides a fascinating description of PyGaze and the significance of eye tracking in research.

Python for Fun This collection is a presentation of several small Python programs. They are aimed at intermediate programmers; people who have studied Python and are fairly comfortable with basic recursion and object oriented techniques. Each program is very short, never more than a couple of pages and accompanied with a write-up. I have found Python to be an excellent language to express algorithms clearly.
