Software Carpentry The Problem Many scientists and engineers spend much of their lives writing, debugging, and maintaining software, but only a handful have ever been taught how to do this effectively: after a couple of introductory courses, they are left to rediscover (or reinvent) the rest of programming on their own. The result? Most spend far too much time wrestling with software when they'd rather be doing research, but still have no idea how reliable or efficient that software is. The Solution This site presents an intensive course on basic software development practices for scientists and engineers. 30 Free Responsive HTML Templates Are you looking for a quick and easy to edit platform to speed up your web design process?

Welcome to Python.org Welcome - Learn Python - Free Interactive Python Tutorial PEP 20 -- The Zen of Python Abstract Long time Pythoneer Tim Peters succinctly channels the BDFL's guiding principles for Python's design into 20 aphorisms, only 19 of which have been written down. The Zen of Python Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex.

Functional Programming HOWTO — Python v2.7.8 documentation In this document, we’ll take a tour of Python’s features suitable for implementing programs in a functional style. After an introduction to the concepts of functional programming, we’ll look at language features such as iterators and generators and relevant library modules such as itertools and functools. Introduction This section explains the basic concept of functional programming; if you’re just interested in learning about Python language features, skip to the next section. Programming languages support decomposing problems in several different ways: Most programming languages are procedural: programs are lists of instructions that tell the computer what to do with the program’s input. The designers of some computer languages choose to emphasize one particular approach to programming. In a functional program, input flows through a set of functions. Functional programming can be considered the opposite of object-oriented programming. Formal provability Modularity Composability Iterators
Perl Though Perl is not officially an acronym,[5] there are various backronyms in use, such as: Practical Extraction and Reporting Language.[6] Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.[7] Since then, it has undergone many changes and revisions. The latest major stable revision of Perl 5 is 5.18, released in May 2013. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. History[edit] Early versions[edit] Wall began work on Perl in 1987, while working as a programmer at Unisys,[9] and released version 1.0 to the comp.sources.misc newsgroup on December 18, 1987.[14] The language expanded rapidly over the next few years. Perl 2, released in 1988, featured a better regular expression engine. Originally the only documentation for Perl was a single (increasingly lengthy) man page. Early Perl 5[edit] Perl 5.001 was released on March 13, 1995. 2000–present[edit]
labs :: 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

C Sharp (programming language) C♯ is intended to be a simple, modern, general-purpose, object-oriented programming language.[6] Its development team is led by Anders Hejlsberg. The most recent version is C♯ 5.0, which was released on August 15, 2012. The ECMA standard lists these design goals for C#:[6] Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (U+266F ♯ music sharp sign (HTML: ♯)) is not present on the standard keyboard, the number sign (U+0023 # number sign (HTML: #)) was chosen to represent the sharp symbol in the written name of the programming language.[8] This convention is reflected in the ECMA-334 C# Language Specification.[6] However, when it is practical to do so (for example, in advertising or in box art[9]), Microsoft uses the intended musical symbol. C# used to have a mascot called Andy (named after Anders Hejlsberg). In the course of its development, the C# language has gone through several versions: C# has the following syntax:
The Hitchhikers Guide to Python! — pythonguide 0.0.1 documentation Greetings, Earthling! Welcome to The Hitchhiker’s Guide to Python. This is a living, breathing guide. This handcrafted guide exists to provide both novice and expert Python developers a best practice handbook to the installation, configuration, and usage of Python on a daily basis. This guide is opinionated in a way that is almost, but not quite, entirely unlike Python’s official documentation. Note The use of Python 3 is highly preferred over Python 2. Let’s get started! Getting Started with Python New to Python? Properly Install Python on your system: Using Virtualenvs with Pipenv: Python Development Environments This part of the guide focus on the Python development environment, and the best-practice tools that are available for writing Python code. Writing Great Python Code This part of the guide focuses on the best-practices for writing Python code. Scenario Guide for Python Applications This part of the guide focuses on tool and module advice based on different scenarios. Additional Notes
Python Programming/Variables and Strings In this section, you will be introduced to two different kinds of data in Python: variables and strings. Please follow along by running the included programs and examining their output. Variables[edit] A variable is something with a value that may change. In simplest terms, a variable is just a box that you can put stuff in. You can use variables to store all kinds of stuff, but for now, we are just going to look at storing numbers in variables. lucky = 7print (lucky)7 This code creates a variable called lucky, and assigns to it the integer number 7. We can also change what is inside a variable. changing = 3print (changing)3 changing = 9print (changing)9 different = 12print (different)12print (changing)9 changing = 15print (changing)15 We declare a variable called changing, put the integer 3 in it, and verify that the assignment was properly done. You can also assign the value of a variable to be the value of another variable. We start out declaring that red is 5, and blue is 10. Solutions
VsPhp This page was copied mindlessly from (Google Cache) Common Ground Both PHP and Python: are interpreted, high level languages with dynamic typing are OpenSource (except where various Zend products, recommended by some, are employed) are supported by large developer communities are easy to learn (compared to C++, Perl) are easy to extend in C, C++ and Java are extremely portable. Compared as Languages What strengths do PHP have that Python doesn't? the 'switch' statement and 'do ... while' construct increment and decrement and assignment operators (assignment is a statement only in Python) the ternary operator/statement (... ? What weaknesses does PHP have that Python doesn't? (more verbose) syntax from C/C++ and Perl, with lots curly braces and dollar signs and "->"-s confused tableau of function names. What does Python have that PHP doesn't? Compared as Web Development Frameworks There are some adverse side effects of this flexibility. Security Python
