TurboGears
TurboGears is a Python web application framework consisting of several WSGI components such as WebOb, SQLAlchemyKajikitemplate language and Repoze. TurboGears is designed around the model–view–controller (MVC) architecture, much like Struts or Ruby on Rails, designed to make rapid web application development in Python easier and more maintainable. Since version 2.3 the framework has also been providing a "minimal mode" which enables it to act as a microframework for usage in environments where the whole stack is not required nor wanted. TurboGears components TurboGears is built on top of numerous disparate libraries and middleware. The default tools have changed between the 1.x, 2.x and 2.3+ series, but most of these components can be used in either as there is support for many alternative configurations. The following are the primary components a developer would interact with. TurboGears 2.x components * SQLAlchemy ( Model) - defines the table structures of the user's d ...

CherryPy
CherryPy is an object-oriented web application framework using the Python programming language. It is designed for rapid development of web applications by wrapping the HTTP protocol but stays at a low level and does not offer much more than what is defined in RFC 7231. CherryPy can be a web server itself or one can launch it via any WSGI compatible environment. It does not deal with tasks such as templating for output rendering or backend access. The framework is extensible with filters, which are called at defined points in the request/response processing. Pythonic interface One of the goals of the project founder, Remi Delon, was to make CherryPy as pythonic as possible. This allows the developer to use the framework as any regular Python module and to forget (from a technical point of view) that the application is for the web. For instance, the common Hello World program with CherryPy 3 would look like: import cherrypy class HelloWorld: def index(self): retu ...

Kid (templating Language)
Kid is a simple template engine (web), template engine for XML-based vocabularies written in Python (programming language), Python. Kid claims to have many of the best features of XSLT, Template Attribute Language, TAL, and PHP, but "with much of the limitations and complexity stamped out". Kid initially acted as the Model–View–Controller, View component of the TurboGears framework in the framework's version 1.x implementation; however, the TurboGears project team has since replaced it with Genshi (templating language), Genshi, citing perceived performance advantages. Kid is used by the Fedora Project in the repoview utility which creates a set of static HTML pages within a Yellowdog Updater, Modified, YUM repository. Example Python part: from kid import Template template = Template(file='mytemplate.kid', title='bar', mylist=['1', '2', '3', '4', '5', '6'] ) print template.serialize() Template part: title goes here item goes here ...

Genshi (templating Language)
Genshi is a template engine for XML-based vocabularies written in Python. Genshi is used to easily insert generated output into XML-based languages, usually HTML, and reuse elements between documents. Genshi's syntax is based on Kid, but its architecture is different. Genshi aims to implement some of its functionality while processing templates faster, by dynamically processing templates using a stream based API, instead of compiling templates to Python code. Genshi can be used with several Python web frameworks, such as CherryPy, TurboGears, Pylons and web2py. Genshi has replaced Kid in the TurboGears 2.x web framework. Genshi markup Genshi makes use of namespaces to embed instructions into HTML. A typical instruction is given as an attribute, with a Python expression inside the quotes. For example, the following will render a paragraph that shows 4: This will be replaced with 4 Because of the use of namespaces, Genshi can be used in WYSIWYG HTML ...

SQLObject
SQLObject is a Python object-relational mapper between a SQL database and Python objects. It is experiencing community popularity, and forms a part of many applications (e.g., TurboGears). It is very similar to Ruby on Rails' ActiveRecord in operation in that it uses class definitions to form table schemas, and utilizes the language's reflection and dynamism to be useful. SQLObject supports a number of common database backends: included in the distribution are MySQL, PostgreSQL, SQLite, Sybase SQL Server, MaxDB, Microsoft SQL Server and Firebird. The first version of SQLObject was publicly released in October 2002.

MochiKit
MochiKit is a light-weight JavaScript library written and maintained by Bob Ippolito. Inspired by the Python networking framework, Twisted, it uses the concept of deferred execution to allow asynchronous behaviour. This has made it useful in the development of interactive web pages which maintain a dialog with the web server, sometimes called Ajax applications. Of particular note is its ability to load and manipulate JSON-encoded data sets, and MochiKit.DOM, a set of functions to easily create dynamic page components. MochiKit forms the foundation of the client-side functionality of the TurboGears Python web-application stack. Perhaps as a result of the author's involvement in the Python community, MochiKit exhibits many idioms familiar to Python programmers, and is commonly used in Python-based web applications.

SQLAlchemy
SQLAlchemy is an open-source SQL toolkit and object-relational mapper (ORM) for the Python programming language released under the MIT License. Description SQLAlchemy's philosophy is that relational databases behave less like object collections as the scale gets larger and performance starts being a concern, while object collections behave less like tables and rows as more abstraction is designed into them. For this reason it has adopted the data mapper pattern (similar to Hibernate for Java) rather than the active record pattern used by a number of other object-relational mappers.iThe architecture of open source applications/ref> History SQLAlchemy was first released in February 2006 Example The following example represents an n-to-1 relationship between movies and their directors. It is shown how user-defined Python classes create corresponding database tables, how instances with relationships are created from either side of the relationship, and finally how the data ca ...

Pylons (web Framework)
Pylons Project is an open-source organization that develops a set of web application technologies written in Python. Initially the project was a single web framework called Pylons, but after the merger with the repoze.bfg framework under the new name Pyramid, the Pylons Project now consists of multiple related web application technologies. Pyramid Pyramid is an open source web framework written in Python and is based on WSGI. It is a minimalistic web framework inspired by Zope, Pylons and Django. Originally called "repoze.bfg", Pyramid gathered attention mostly in the Zope and Plone community as the Open Society Institute's KARL project migrated from Plone to BFG. In 2010 it was announced that the Pylons framework will move over to using BFG as a base in version 1.5. As a result of the inclusion of BFG into the Pylons project, BFG was renamed Pyramid. Features Pyramid is a minimalistic, platform-independent web framework. It is persistence agnostic and is integrated both with ...

Python Paste
Python Paste, often simply called paste, is a set of utilities for web development in Python. Paste has been described as "a framework for web frameworks". The Python Paste package contains Python modules that help in implementing WSGI middleware. The package includes a WSGI wrapper for CGI applications. It also includes a simple webserver that can produce WSGI requests. WSGI middleware The WSGI standard is an interface that allows applications to use Python code to handle HTTP requests. A WSGI application is passed a Python representation of an HTTP request by an application, and returns content which will normally eventually be rendered by a web browser. A common use for this is when a web server serves content created by Python code. There are, however, other uses: WSGI middleware is Python code that receives a WSGI request and then performs logic based upon this request, before passing the request on to a WSGI application or more WSGI middleware. WSGI middleware appears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently r ...

Web Server Gateway Interface
The Web Server Gateway Interface (WSGI, pronounced ''whiskey'' or ) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language. The current version of WSGI, version 1.0.1, is specified in Python Enhancement Proposal (PEP) 3333. WSGI was originally specified as PEP-333 in 2003. PEP-3333, published in 2010, updates the specification for . Background In 2003, Python web frameworks were typically written against only CGI, FastCGI, mod_python, or some other custom API of a specific web server. To quote PEP 333: Python currently boasts a wide variety of web application frameworks, such as Zope, Quixote, Webware, SkunkWeb, PSO, and Twisted Web -- to name just a few. This wide variety of choices can be a problem for new Python users, because generally speaking, their choice of web framework will limit their choice of usable web servers, and vice versa...

Apache HTTP Server
The Apache HTTP Server ( ) is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. The vast majority of Apache HTTP Server instances run on a Linux distribution, but current versions also run on Microsoft Windows, OpenVMS, and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems, including ports to mainframes. Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites. , Netcraft estimated that Apache served 23.04% of the million busiest websites, while Nginx served ...

JSON
JSON (JavaScript Object Notation, pronounced ; also ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) specifies "Pronounced , as in ' Jason and ...
