Python Programming – Python Introduction
Python is a powerful high-level, interpreted, interactive, and object-oriented scripting language. It was designed to be easily readable; it uses English keywords frequently whereas other languages use punctuation. It has fewer syntactical constructions than other languages. It has a simple easy-to-use syntax to learn computer programming.

Features of Python Language
(a) Python is Interpreted: This means that it is processed at runtime by the interpreter, and you do not need to compile your program before executing it. Interpreted languages run directly from source code that humans generate whereas programs written in compiled languages, like C++, must be translated into machine code before they can be executed. Python is considered an interpreted language because Python programs are executed by an interpreter.
(b) Python is Interactive: This means that you can actually work at a Python prompt and interact with the interpreter directly to execute your programs and get the output.
(c) Python is Object-oriented: Python supports procedure-oriented programming as well as object-oriented programming. In procedure-oriented languages, the program is built around procedures or functions, which are reusable codes of programs. In object-oriented languages, the program is built around objects which combine data and functionality.
(d) Python is Beginner’s Language: Python is a great language for beginner programmers as the language is interpreted, hence gives immediate, results. It also supports the development of a wide range of applications, from simple text processing to WWW (World Wide Web) browsers to games.
(e) Python is Complete Language: When you install Python, you need not download and install additional libraries. All types of required functionalities are available through various mod¬ules of the Python standard library. Thus, it is also said that – Python follows “Batteries Included”
Philosophy.
History of Python
Python was developed by Guido van Rossum in the late eighties and early nineties at the National Research Institute for Mathematics and Computer Science in the Netherlands. Python 1.0 was released in November 1994. In 2000, Python 2.0 was released.
Later on, Python 3.0 was released in 2008. The most recent major version of Python is Python 3. Python 3 is not backward compatible with Python 2. It is available for Windows, Mac OS, and most of the versions of the Linux operating system. It is well supported and freely available at www.python.org.
Python is derived from many other languages, including ABC, Modula-3, C, C++, Algol-68, Small-Talk, and UNIX shell, and other scripting languages.
It is copyrighted. Similar to Perl, Python source code is now available under the GNU General Public License (GPL).
- Python 3.0 has new major features, including a full garbage collector and support for Unicode.
Who uses Python?
Python provides powerful programming features and is widely used. Companies and organizations that use Python include YouTube, Google, Yahoo, and NASA. Python is used for web development (server-side), software development, mathematics, and system scripting. The popular YouTube video sharing service is largely written in Python. Google makes extensive use of Python in its web search systems. Dropbox storage service codes both its server and desktop client software, primarily, in Python. The NSA uses Python for cryptography and intelligence analysis. Today Python has become the language of choice for data scientists. Python libraries like NumPy, Pandas, and Matplotlib are extensively used in the process of data analysis. Machine Learning is another key application area of Python. Some of the real-world applications of machine learning include medical diagnosis, sales prediction, etc. Python can also be used to develop Android apps.
