- 5. INTRODUCTION Python is ahigh-level, interpreted and general- purpose dynamic programming language that focuses on code readability. The syntax in Python helps the programmers to do coding in fewer steps as compared to Java or C++. The language founded in the year 1991 by the developer Guido Van Rossum has the programming easy and fun to do.

- 11. INTRODUCTION The Python iswidely used in bigger organizations because of its multiple programming paradigms. They usually involve imperative and object-oriented functional programming. It has a comprehensive and large standard library that has automatic memory management and dynamic features.
- 12. INTRODUCTION Python is ageneral-purpose language, which means it can be used to build just about anything, which will be made easy with the right tools/libraries. Professionally, Python is great for backend web development, data analysis, artificial intelligence, and scientific computing. Many developers have also used Python to build productivity tools, games, and desktop apps, so there are plenty of resources to help you learn how to do those as well.
- 13. HISTORY OF PYTHON Workon Python began in late 1989 by Guido van Rossum, then at Centrum Wiskunde (Pronounce as viskulu meaning mathematics) & Informatica CWI in the Netherlands, and eventually released for public distribution in early 1991.
- 14. HISTORY OF PYTHON Pythonwas conceived in the late 1980s, and its implementation began in December 1989 by Guido van Rossum at Centrum Wiskunde (Pronounce as viskulu meaning mathematics) & Informatica (CWI) in the Netherlands as a successor to the ABC language (itself inspired by SETL) capable of exception handling and interfacing with the Amoeba operating system. Where was Python created?
- 15. HISTORY OF PYTHON Sincemost modern OS are written in C, compilers/interpreters for modern high-level languages are also written in C. Python is not an exception - its most popular/"traditional" implementation is called CPython and is written in C. There are other implementations: IronPython (Python running on .NET). What language is Python written in?
- 16. HISTORY OF PYTHON Howdid it all begin? Innovative Languages are usually born from one of two motivations: (1) A large well-funded research project or (2) General frustration due to the lack of tools that were needed at the time to accomplish mundane and/or time-consuming tasks, many of which could be automated.
- 17. HISTORY OF PYTHON How did it all begin? Innovative At the time, van Rossum was a researcher with considerable language design experience with the interpreted language ABC, also developed at CWI (Centrum Wiskunde (Pronounce as viskulu meaning mathematics) & Informatica.P.O.Box 940791090 GB Amsterdam NETHERLANDS), but he was unsatisfied with its ability to be developed into something more.
- 18. HISTORY OF PYTHON How did it all begin? Innovative Some of the tools he envisioned were for performing general system administration tasks, so he also wanted access to the power of system calls that were available through the Amoeba distributed operating system. Although an Amoeba-specific language was given some thought, a generalized language made more sense, and late in 1989, the seeds of Python were sown.
- 19. HISTORY OF PYTHON What is CWI? Where it is located? Centrum Wiskunde (Pronounce as viskulu meaning mathematics) & Informatica (CWI) is the national research institute for mathematics and computer science in the Netherlands. Founded in 1946, CWI is part of the Institutes Organisation of NWO, NWO-I. While located at Amsterdam Science Park, this institute has strong international links, and enjoy a global reputation for innovative research.

- 23. Where does thePython name come from?
- 24. When he began implementingPython, Guido van Rossum was also reading the published scripts from “Monty Python's Flying Circus”, a BBC comedy series from the 1970s. Van Rossum thought he needed a name that was short, unique, and slightly mysterious, so he decided to call the language Python. Where does the Python name come from?
- 25. WHY COMPANIES PREFERPYTHON?
- 26. Python has topthe charts in the recent years over other programming languages like C, C++ and Java and is widely used by the programmers. The language has undergone a drastic change since its release 25 years ago as many add-on features are introduced. The Python 1.0 had the module system of Modula-3 and interacted with Amoeba Operating System with varied functioning tools. Python 2.0 introduced in the year 2000 had features of garbage collector and Unicode Support. WHY COMPANIES PREFER PYTHON?
- 27. Python 3.0 introducedin the year 2008 had a constructive design that avoids duplicate modules and constructs. With the added features, now the companies are using Python 3.5. The software development companies prefer Python language because of its versatile features and fewer programming codes. Nearly 14% of the programmers use it on the operating systems like UNIX, Linux, Windows and Mac OS. WHY COMPANIES PREFER PYTHON?
- 28. The programmers ofbig companies use Python as it has created a mark for itself in the software development with characteristic features like: Interactive Interpreted Modular Dynamic Object-oriented Portable High level Extensible in C++ & C WHY COMPANIES PREFER PYTHON?

- 97. PYTHON SHELL What isShell? A shell is usually an "interactive shell", usually termed a REPL which stands for "Read - Execute - Print - Loop" Most interpreted languages offer a REPL interface - whether its LISP, python, BASIC or Javascript or even DOS batch language or Unix Shells. The interpreter is what actually executes the lines of code.
- 98. PYTHON SHELL What isPython Shell or Python Interactive Shell? The Python interpreter can be used from an interactive shell. The interactive shell is also interactive in the way that it stands between the commands or actions and their execution. ... Python offers a comfortable command line interface with the Python shell, which is also known as the "Python interactive shell".

- 100. PYTHON BASIC MODES Whatare the basic modes of python? Python has two basic modes: 1) Script and 2) Interactive.
- 101. PYTHON BASIC MODES 1)Script Mode: The normal mode is the mode where the scripted and finished .py files are run in the Python interpreter.
- 102. PYTHON BASIC MODES 2)Interactive Mode: Interactive mode is a command line shell which gives immediate feedback for each statement, while running previously fed statements in active memory.
- 103. SCRIPT What is Script? Scriptsare reusable. Basically, a script is a text file containing the statements that comprise a Python program. Once you have created the script, you can execute it over and over without having to retype it each time. Scripts are editable.
