Beautiful Soup (HTML Parser)
Beautiful Soup is a Python package for parsing HTML and XML documents, including those with malformed markup. It creates a parse tree for documents that can be used to extract data from HTML, which is useful for web scraping. Beautiful Soup was started by Leonard Richardson, who continues to contribute to the project, and is additionally supported by Tidelift, a paid subscription to open-source maintenance. Code example Beautiful Soup represents parsed data as a tree which can be searched and iterated over with ordinary Python loops. The example below uses the Python standard library's urllib to load Wikipedia's main page, then uses Beautiful Soup to parse the document and search for all links within. #!/usr/bin/env python3 # Anchor extraction from HTML document from bs4 import BeautifulSoup from urllib.request import urlopen with urlopen('https://en.wikipedia.org/wiki/Main_Page') as response: soup = BeautifulSoup(response, 'html.parser') for anchor in soup.find_al ...

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 ran ...

Alice's Adventures In Wonderland
''Alice's Adventures in Wonderland'' (commonly ''Alice in Wonderland'') is an 1865 English novel by Lewis Carroll. It details the story of a young girl named Alice who falls through a rabbit hole into a fantasy world of anthropomorphic creatures. It is seen as an example of the literary nonsense genre. The artist John Tenniel provided 42 wood-engraved illustrations for the book. It received positive reviews upon release and is now one of the best-known works of Victorian literature; its narrative, structure, characters and imagery have had widespread influence on popular culture and literature, especially in the fantasy genre. It is credited as helping end an era of didacticism in children's literature, inaugurating a new era in which writing for children aimed to "delight or entertain". The tale plays with logic, giving the story lasting popularity with adults as well as with children. The titular character Alice shares her given name with Alice Liddell, a girl Carrol ...

Software Using The MIT License
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comparison Of HTML Parsers
HTML parsers are software for automated Hypertext Markup Language (HTML) parsing. They have two main purposes: * HTML traversal: offer an interface for programmers to easily access and modify the "HTML string code". Canonical example: DOM parsers. * HTML clean: to fix invalid HTML and to improve the layout and indent style of the resulting markup. Canonical example: HTML Tidy HTML Tidy is a console application for correcting invalid HyperText Markup Language (HTML), detecting potential web accessibility errors, and for improving the layout and indent style of the resulting markup. It is also a cross-platform library .... : * Latest release (of significant changes) date. : ** ''sanitize'' (generating standard-compatible web-page, reduce spam, etc.) and ''clean'' (strip out surplus presentational tags, remove XSS code, etc.) HTML code. : *** Updates HTML4.X to XHTML or to HTML5, converting deprecated tags (ex.

Wikipedia
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations. Wikipedia was launched by Jimmy Wales and Larry Sanger on January 15, 2001. Sanger coined its name as a blend of ''wiki'' and '' encyclopedia''. Wales was influenced by the " spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton. Initially available only in English, versions in other languages were quickly developed. Its combi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as sur ...

Standard Library
In computer programming, a standard library is the library (computing), library made available across Programming language implementation, implementations of a programming language. These libraries are conventionally described in programming language specifications; however, contents of a language's associated library may also be determined (in part or whole) by more informal practices of a language's community. Overview A language's standard library is often treated as part of the language by its programmer, users, although the designers may have treated it as a separate entity. Many language specifications define a core set that must be made available in all implementation#Computer Science, implementations, in addition to other portions which may be optionally implemented. The line between a language and its libraries therefore differs from language to language. Indeed, some languages are designed so that the meanings of certain syntactic constructs cannot even be described with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Flow
In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an '' imperative programming'' language from a ''declarative programming'' language. Within an imperative programming language, a ''control flow statement'' is a statement that results in a choice being made as to which of two or more paths to follow. For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements. A set of statements is in turn generally structured as a block, which in addition to grouping, also defines a lexical scope. Interrupts and signals are low-level mechanisms that can alter the flow of control in a way similar to a subroutine, but usually occur as a response to some external stimulus or event (that can occur asynch ...
