pYTHON

Python is an interpreted high-level general-purpose programming language. Its design philosophy emphasizes code readability with its use of significant indentation. Its language constructs as well as its object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.[30]

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.[31]

Python is a multi-paradigm programming languageObject-oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming[57] and metaobjects (magic methods)).[58] Many other paradigms are supported via extensions, including design by contract[59][60] and logic programming.[61]

Python uses dynamic typing and a combination of reference counting and a cycle-detecting garbage collector for memory management.[62] It also features dynamic name resolution (late binding), which binds method and variable names during program execution.

Python’s design offers some support for functional programming in the Lisp tradition. It has filter,mapandreduce functions; list comprehensionsdictionaries, sets, and generator expressions.[63] The standard library has two modules (itertools and functools) that implement functional tools borrowed from Haskell and Standard ML.[64]

The language’s core philosophy is summarized in the document The Zen of Python (PEP 20), which includes aphorisms such as:[65]

  • Beautiful is better than ugly.
  • Explicit is better than implicit.
  • Simple is better than complex.
  • Complex is better than complicated.
  • Readability counts.

pYTHON HISTORY

Python was conceived in the late 1980s[38] by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands as a successor to ABC programming language, which was inspired by SETL,[39] capable of exception handling and interfacing with the Amoeba operating system.[10] Its implementation began in December 1989.[40] Van Rossum shouldered sole responsibility for the project, as the lead developer, until 12 July 2018, when he announced his “permanent vacation” from his responsibilities as Python’s Benevolent Dictator For Life, a title the Python community bestowed upon him to reflect his long-term commitment as the project’s chief decision-maker.[41] In January 2019, active Python core developers elected a 5-member “Steering Council” to lead the project.[42] As of 2021, the current members of this council are Barry Warsaw, Brett Cannon, Carol Willing, Thomas Wouters, and Pablo Galindo Salgad For More Click Here o.[43]

Python 2.0 was released on 16 October 2000, with many major new features, including a cycle-detecting garbage collector and support for Unicode.[44]

Python 3.0 was released on 3 December 2008. It was a major revision of the language that is not completely backward-compatible.[45] Many of its major features were backported to Python 2.6.x[46] and 2.7.x version series. Releases of Python 3 include the 2to3 utility, which automates (at least partially) the translation of Python 2 code to Python 3.[47]

Python 2.7’s end-of-life date was initially set at 2015 then postponed to 2020 out of concern that a large body of existing code could not easily be forward-ported to Python 3.[48][49] No more security patches or other improvements will be released for it.[50][51] With Python 2’s end-of-life, only Python 3.6.x[52] and later are supported.

Python 3.9.2 and Link 2  3.8.8 were expedited[53] as all versions of Python (including 2.7[54]) had security issues, leading to possible remote code execution[55] and web cache poisoning.[56]

Advantages of Python

1. Easy to Read, Learn and Write

Python is a high-level programming language that has English-like syntax. This makes it easier to read and understand the code.

Python is really easy to pick up and learn, that is why a lot of people recommend Python to beginners. You need less lines of code to perform the same task as compared to other major languages like C/C++ and Java.

2. Improved Productivity

Python is a very productive language. Due to the simplicity of Python, developers can focus on solving the problem. They don’t need to spend too much time in understanding the syntax or behavior of the programming language. You write less code and get more things done.

3. Interpreted Language

Python is an interpreted language which means that Python directly executes the code line by line. In case of any error, it stops further execution and reports back the error which has occurred.

Histogram :

The histogram represents the frequency of occurrence of specific phenomena which lie within a specific range of values and arranged in consecutive and fixed intervals.
In below code histogram is plotted for Age, Income, Sales. So these plots in the output shows frequency of each unique value for each attribute.
