Introduction to Python

Python is a high-level, general-purpose programming language with an elegant syntax that allows programmers to focus more on problem-solving than on syntax errors. One of the primary goals of Python Developers is to keep it fun to use. Python has become a big buzz in the field of modern software development, infrastructure management, and especially in Data Science and Artificial Intelligence. Most recently, Python has risen to the top 3 list of TIOBE index of language popularity.

Python History

Python was initially founded in the late 1990s by Guido van Rossum. He decided to create a language in 1989. He wanted to build a programming language that could resolve the issues the programmers were facing at that time. Within 5 years, he released the first version of the Python programming language which not only solves many flaws but he made it with easily readable syntax. Guido van Rossum has named this programming language “Python” in honor of his favorite comedian “The Pythons” in the “Monty Python’s Flying Circus” show.

Although it did not get popular at first after Google announced that it has used Python for its internal development programming, it started getting in-demand. This was a turning point for the Python programming language.

Thereafter, many programmers, developers started using Python as their primary programming language which eventually became the best programming language for any Machine Learning algorithms, Data Science projects, and many more. Today, It is one of the most widely used programming languages for any IT application.

Why choose Python over any other languages?

Popularity over the years (2004–2017):

When compared to any other high-level programming languages such as C++ and Java, it requires the programmer to develop lesser codes. Python is designed to be simple and easy to read and write.

Python can be utilized for a wide range of applications such as scripting, developing, and testing. Because of its elegance and simplicity, Dropbox, Google, Quora, Hewlett-Packard, and so many other top tech companies have already implemented Python.

With the growing trend of Data Science and Machine Learning, Python has equally become one of the most important scripting languages in the 21st century, because of its wide range of libraries and frameworks.

Features of Python

Some of the common features of the Python programming language are:

  • Object-Oriented: Python was created with an Object-oriented programming approach which helps in writing clean and clear code. Object-oriented programming can be achieved through Python Class.
  • Use of Interpreter: Python codes are interpreted line by line at a time using the Interpreter. This also helps in debugging.
  • Free and Open-source: This is a free and open-source programming language so everyone can use it.
  • Simple: It is simple to use as it is just like an English sentence resulting in fast coding and execution.
  • Can be Integrated: It can be integrated with other programming languages like C, C+, Java, and many more. This will also teach you most of the programming concepts.
  • Cross-platform: Python is a cross-platform programming language which means it allows you to use it on any platform like Windows, Linux, Mac, Unix, etc.
  • Large library: Python’s ecosystem is large and growing, with a wide range of open-source packages and libraries. There are over 137,000 Python libraries.
  • Elegant Syntax: Python has a simple syntax that improves readability and lowers code maintenance costs which makes code elegant and straightforward.

Characteristics of Python Programming

Some of the characteristics of Python programming which make it a popular language are:

  • There’s a rich collection of Python Data Types.
  • Python is a platform-independent scripted language that comes with features to have complete access to operating system APIs.
  • When compared with other programming languages, Python provides more run-time flexibility.
  • The basic text manipulation facilities of Awk and Perl are also included in Python.
  • There is a Python Module where you can have more than one class and free function.
  • Libraries available in Python are cross-platform compatible and can run on platforms such as Windows, Linux, or macOS.
  • Python can be easily compiled to byte-code; that’s the reason it is most suitable for building large applications.
  • Python also provides features to support functional and structured programming, as well as OOP concepts.
  • Python supports an interactive mode that allows interactive testing and debugging for snippets of code.
  • In Python, there is no editing, debugging, testing, and compilation steps, so it is very fast.
