Python tutorial - Introduction to Python

What is Python?

Python is a general-purpose programming language, created by Guido van Rossum in the year 1991, and ever since it has become one of the most widely used languages along with Java, PHP, etc. It’s a high-level programming language that includes built-in data structure and combined with dynamic typing which makes it a more preferable language for fast application development or to connect the existing elements in a script.
Python is very simple, easy-to-learn, and supports multiple programming paradigms including the Object-oriented, functional, imperative, procedural just to name a few. Programmers often fall in love with this language for the enhanced productivity it provides. Some of its special features include an automatic memory system and dynamic type system which makes this language uncomplicated and more readable.


What is Python used for?


Whenever you ask someone-“What programming language should I learn?” The most common answer would be Python. Because it is very easy to learn and is one of the simplest languages we have right now. It allows you to use English keywords instead of some punctuation, it’s readable and the clean code base will enhance your productivity.
The built-in libraries and web frameworks such as Django, Flask and Pyramid, will make the perfect backend for web developments and application projects, by allowing you to write a little number of codes thus shortening the time you spend on your projects



Artificial Intelligence is the intelligence displayed by machines. It is one of the latest technologies that have built a craze among tech geeks. When it comes to AI, Python is the most suited language for it. Hence, has taken the big lead into this world of Artificial Intelligence.
Python has some special frameworks, libraries, and tools dedicated to building an AI that can replace human efforts. One major benefit of this programming language is that it doesn’t need to be compiled into machine language instruction before execution and allows the programmer to run the program directly. Python is available for all operating systems and is an open-source titled CPython. Hence, it is the most preferred language for creating powerful AI.



If you have an existing game or want to add a scripting engine for more flexibility then Python will prove to be the best choice. Python and Pygame framework offers rapid game prototyping which is beginner-friendly and comes with a wide range of Python Game libraries that you can use to create some stunning and powerful games.



Python is also used in Data science and scientific research and also has several science-specific libraries such as:
Graph-tool for statistical analysis of graphs
Biopython for biology
Psychopy for neuroscience
Astropy for astronomy
And many more. Its simplicity and robust capabilities make it an outstanding language choice for researchers and analysts. To know more check out the list of Python’s scientific libraries.



According to a survey released by HackerRank in 2016, the biggest industries such as HIS Markit, Morgan Stanley are hiring developers who are expert in Python language. Python was one of the top three most popular languages in the financial sector and when it came to FinTech, Python dominated the list.
It’s not just the FinTech companies; Python is used all over the financial industry. Some of the major companies that use python are Robinhood, Stripe, and Zopa.
