== Introduction ==
'''Python''' is an interpreted, high-level programming language known for its easy readability and simplicity. It was created by Guido van Rossum and first released in 1991. Python emphasizes code readability and allows programmers to express concepts in fewer lines of code compared to other languages. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. With its comprehensive standard library and an active community, Python has grown to become one of the most popular programming languages in the world, widely used in various domains, including web development, data analysis, artificial intelligence, scientific computing, and automation.


'''Python''' is a high-level, interpreted, general-purpose [[programming language]] known for its readability and simplicity. Created by [[Guido van Rossum]] and first released in 1991, Python emphasizes code readability through its use of significant whitespace and a clear, expressive syntax. It supports multiple [[programming paradigms]], including [[procedural programming]], [[object-oriented programming]], and [[functional programming]]. Python's extensive [[standard library]] and dynamic typing make it a versatile tool for a wide range of applications, from web development to scientific computing.
== History ==
Python's history can be traced back to the late 1980s when Guido van Rossum began working on it as a successor to the ABC programming language. The language was designed to address the shortcomings of ABC while retaining its features. Python 1.0 was released in February 1991, introducing fundamental concepts such as exceptions, functions, and the core data types of lists and dictionaries. In the years that followed, Python underwent several enhancements.


Python is an open-source language with a large, active community that contributes to its development and maintenance. Its design philosophy, summarized in the document ''[[The Zen of Python]]'', prioritizes simplicity and explicitness. Python is widely regarded as one of the easiest languages for beginners to learn, while also being powerful enough for advanced users.
=== Python 2.x ===
Python 2.0 was released in October 2000 and included many new features, such as list comprehensions and garbage collection. The Python Software Foundation (PSF) was created in 2001 to promote, protect, and advance the Python programming language. Python 2 became widely adopted and was supported until January 1, 2020, at which point it reached its end of life, leading the community to fully transition to Python 3.


== History or Background ==
=== Python 3.x ===
Python 3.0 was launched in December 2008, offering significant improvements over its predecessor, primarily emphasizing better Unicode support and a more consistent standard library. Python 3 was not backward compatible with Python 2, which caused some controversy in the community. Notable features introduced in Python 3 include the print function as a standard function, rather than a statement, and the introduction of type hints. Following the transition period, Python 3's adoption has steadily increased, with its usage in various sectors proliferating.


Python was conceived in the late 1980s by Guido van Rossum at [[Centrum Wiskunde & Informatica]] (CWI) in the Netherlands as a successor to the [[ABC (programming language)|ABC language]]. Van Rossum aimed to create a language that combined the best features of existing languages while addressing their shortcomings. The first public release, Python 0.9.0, was made in February 1991. The language was named after the British comedy series ''[[Monty Python's Flying Circus]]'', reflecting van Rossum's playful approach to programming.
== Features ==
Python encompasses a range of features that make it appealing for both beginners and experienced developers. Β 


Key milestones in Python's development include:
=== Readability ===
* '''Python 1.0''' (1994): Introduced functional programming tools like [[lambda calculus|lambda]], [[map (higher-order function)|map]], [[filter (higher-order function)|filter]], and [[reduce (higher-order function)|reduce]].
One of Python's hallmark features is its emphasis on readability. The language's syntax mimics natural language and is designed in a way that reduces the cognitive load on the programmer. This readability fosters better understanding and collaboration among developers, making it easier to maintain and share code.
* '''Python 2.0''' (2000): Added features such as [[list comprehension]]s, garbage collection, and Unicode support.
* '''Python 3.0''' (2008): A major, backward-incompatible release that addressed inconsistencies in Python 2.x. It emphasized removing redundant features and improving clarity.


The transition from Python 2 to Python 3 was gradual, with Python 2 reaching [[end-of-life (product)|end-of-life]] in 2020. Today, Python 3 is the standard, with regular updates introducing new features and optimizations.
=== Dynamic Typing ===
Python employs dynamic typing, which allows developers to write code without the need to explicitly declare variable types. This flexibility enables rapid prototyping and reduces the amount of boilerplate code required. However, dynamic typing can also lead to runtime errors that could have been caught at compile time in statically typed languages.


== Technical Details or Architecture ==
=== Extensive Libraries ===
Python boasts an extensive standard library that encompasses modules and packages for a wide variety of tasksβ€”from file I/O to web development and data manipulation. The library simplifies many programming tasks, reducing the need to write code from scratch. Moreover, the Python Package Index (PyPI) features thousands of additional third-party libraries, which extend Python's capabilities.


=== Syntax and Semantics ===
=== Interpreted Language ===
Python's syntax is designed to be intuitive and readable. Key features include:
As an interpreted language, Python executes code line-by-line rather than compiling it into machine code. This characteristic makes the development process faster and easier for debugging. The interactive shell allows users to test snippets of code in real-time, which is particularly helpful for learning and experimentation.
* '''Indentation''': Python uses whitespace to delimit blocks of code, eliminating the need for braces or keywords like ''begin'' and ''end''.
* '''Dynamic typing''': Variables do not require explicit type declarations, and their types can change during runtime.
* '''Interpreted execution''': Python code is executed line-by-line by the [[Python interpreter]], making debugging and development faster.


Example of Python syntax:
=== Multi-paradigm Support ===
def greet(name):
Python supports multiple programming paradigms, enabling developers to choose the most suitable approach for their projects. Object-oriented programming facilitates model representation, while functional programming features, such as lambda functions and map-reduce operations, allow for more concise and expressive code.
Β  Β  print(f"Hello, {name}!")


greet("World")
== Usage and Applications ==
Β 
Python's diverse range of applications is one of the key factors contributing to its popularity.
=== Memory Management ===
Python employs automatic [[memory management]] through [[reference counting]] and a [[garbage collection (computer science)|garbage collector]]. This reduces the risk of [[memory leak]]s and simplifies development. The [[Global Interpreter Lock]] (GIL) is a notable feature of Python's [[CPython]] implementation, which can affect performance in multi-threaded applications.
Β 
=== Implementations ===
The primary implementation of Python is [[CPython]], written in [[C (programming language)|C]]. Other implementations include:
* '''[[Jython]]''': Runs on the [[Java Virtual Machine]] (JVM).
* '''[[IronPython]]''': Integrates with the [[.NET Framework]].
* '''[[PyPy]]''': A [[just-in-time compilation|JIT]]-compiled implementation for improved performance.
Β 
=== Standard Library ===
Python's [[standard library]] includes modules for:
* File I/O (e.g., [[os module|os]], [[sys module|sys]])
* Data serialization (e.g., [[pickle module|pickle]], [[json module|json]])
* Networking (e.g., [[socket module|socket]], [[http module|http]])
* Mathematical operations (e.g., [[math module|math]], [[random module|random]])
