Python beginner's mistakes

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. To put it another way, the mistakes in this article are often cases of "the wrong tool for the job", rather than coding errors or sneaky language traps. Mistake 1: trying to do low-level operations Python is sometimes described as a VHLL, a Very High-Level Language. This doesn't mean that it isn't possible to do these things with Python; but it's probably just not the right language for these jobs. Mistake 2: writing "language X" code in Python This is a mistake that is almost unavoidable. Some notorious symptoms of "language X" code, and the languages that may cause them: The point here is not to slam the language that you're used to (although that is always fun ;-). This one requires some clarification. Some advice Related:  Langage python

Python Course: Modular Programming and Modules Modular Programming If you want to develop programs which are readable, reliable and maintainable without too much effort, you have use some kind of modular software design. Especially if your application has a certain size. There exists a variety of concepts to design software in modular form. But how do we create modules in Python? def fib(n): if n == 0: return 0 elif n == 1: return 1 else: return fib(n-1) + fib(n-2) def ifib(n): a, b = 0, 1 for i in range(n): a, b = b, a + b return a We can import this module in the interactive python shell and call the functions by prefixing them with "fibonacci >>> import fibonacci >>> fibonacci.fib(30) 832040 >>> fibonacci.ifib(100) 354224848179261915075L >>> fibonacci.ifib(1000) 43466557686937456435688527675040625802564660517371780402481729089536555417949051890403879840079255169295922593080322634775209689623239873322471161642996440906533187938298969649928516003704476137795166849228875L >>> >>> fib = fibonacci.ifib >>> fib(10) 55 >>> More on Modules

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. Python is the language where you don’t have to focus on syntax much and focus on code part only. Ruby language was discovered by one Japanese Scientist “Matz” in 1995. Ruby is complete object oriented with classes, objects, methods etc. Python web development Python is the language where you don’t have to focus on syntax much and focus on code part only. Python popularity over Ruby Ruby gained popularity after release of Ruby on rails in 2005. Another reason that makes Python popular is its architecture.

The Django Book Learn Python in 10 minutes | Stavros' Stuff NOTE: If you would like some Python development done, my company, Stochastic Technologies, is available for consulting. This tutorial is available as a short ebook. The e-book features extra content from follow-up posts on various Python best practices, all in a convenient, self-contained format. All future updates are free for people who purchase it. Preliminary fluff So, you want to learn the Python programming language but can't find a concise and yet full-featured tutorial. Properties Python is strongly typed (i.e. types are enforced), dynamically, implicitly typed (i.e. you don't have to declare variables), case sensitive (i.e. var and VAR are two different variables) and object-oriented (i.e. everything is an object). Getting help Help in Python is always available right in the interpreter. >>> help(5)Help on int object:(etc etc) >>> dir(5)['__abs__', '__add__', ...] >>> abs. Syntax Python has no mandatory statement termination characters and blocks are specified by indentation. Strings

Javascript in Modern Web Design In today's web design, Javascript is a must-have component. Aside from its functionality, Javascript can enhance user experience by creating transitional effects such as fading and sliding animation. Thanks to the open source Javascript frameworks, we don't need to write custom Javascript from scratch anymore. Here are 47 Javascript plugins that you can use to enhance the user experience and functionality of your website. The Two Popular Javascript Frameworks Right now, the two commonly used Javascript frameworks are: jQuery and MooTools. Loading ... Image Zoom and Popup Lightbox You're probably very familiar with Lightbox — a light Javascript used to display overlay images on the current page. jQuery lightBox Plugin This is exactly the same as Lightbox JS, but written on top of jQuery library. Thickbox Thickbox is a jQuery plugin that is very similar to Lightbox, but comes with more features. Note: Web Designer Wall uses Thickbox to display the gallery images and tutorial demos.

Planet Python 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. Most of the time, where people look is also where they're attention is. Tell us about you and your work. There are quite a few.

Invent Computer Games with Python The Python Tutorial — Python v2.6.5 documentation Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation. The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). This tutorial introduces the reader informally to the basic concepts and features of the Python language and system.
