Welcome to Python.org Welcome - Learn Python - Free Interactive Python Tutorial 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]

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:
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
Why Python Should Be The First Programming Language You Learn / Python / The Hello World Program Why should Python be the first programming language you learn? It’s awesome. That’s all you need to know. You can stop reading here and start coding now. Of course, you want to know more. Besides being awesome, Python should be your first programming language because you will quickly learn how to think like a programmer. Python is easy to learn. And here’s code with the same output in Python 3: Brilliant, right? Perhaps you’ve already tried to learn a programming language. Once you’ve got the basics down, you’re going to find yourself bored with outputting text and crunching numbers. In case I was too subtle, it’s important to point out that Pythonistas (as they are known) are a funny bunch. We at The Hello World Program advocate GNU/Linux operating systems, but we know that’s not for everyone. Now, for an added challenge: in Python, write a program that reads this blog entry and counts the number of times I used the words “easy” and “awesome”.
C# Programming C sharp musical note Introduction[edit] Main introduction: C Sharp Programming/Foreword Foreword A description of the C# language and introduction to this Wikibook. Getting started with C# A simple C# program and where to get tools to compile it. Basics[edit] Basic syntax Describes the basics in how the applications you write will be interpreted. Naming conventions Quickly describes the generally accepted naming conventions for C#. Variables The entities used to store data of various shapes. Operators Summarizes the operators, such as the '+' in addition, available in C#. Data structures Enumerations, structs, and more. Control statements Loops, conditions, and more. Exceptions Responding to errors that can occur. Classes[edit] Namespaces Giving your code its own space to live in. Classes The blueprints of objects that describes how they should work. Objects Cornerstones of any object-oriented programming language, objects are the tools you use to perform work. Encapsulation and accessor levels Inheritance Generics
Heavy usage of Python at Google PHP Scripting language created in 1994 PHP is a general-purpose scripting language geared towards web development.[8] It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995.[9][10] The PHP reference implementation is now produced by the PHP Group.[11] PHP was originally an abbreviation of Personal Home Page,[12][13] but it now stands for the recursive initialism PHP: Hypertext Preprocessor.[14] The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. The PHP language has evolved without a written formal specification or standard, with the original implementation acting as the de facto standard that other implementations aimed to follow. History[edit] Early history[edit] PHP development began in 1993[9] when Rasmus Lerdorf wrote several Common Gateway Interface (CGI) programs in C,[20][21] which he used to maintain his personal homepage. <!
