Learn Python Programming

Whether you are a well versed programmer or just a beginner who doesn't have any programming experience, Python should be your first programming language of choice. The reason is it is a high-level language unlike C/C++ which means it is easy to learn, write or understand as it is akin to any normal language like English. Python is a dynamically typed and interpreted language which means the code made in Python is simple, less size, easier to read as it is free from clutter & boiler plate code used in other high level languages like Java. Python can also be used to make scripts and automate your stuff. Infact many operating systems like Linux, Mac supply Python as a standard component. Python is growing really fast and big time and it makes a lot of sense to invest your time in learning a growing programming language if you are just starting your programming career. This not only helps you to get a job quickly but also will also accelerate your career growth.

Created in 1991, Python is older than Java but lately gained popularity and wide spread usage due to its simple structure and ability to learn easily even though you don't have any prior programming experience. Python's large standard library is one of its greatest strengths as it provides tools suited to many tasks. For Internet-facing applications, many standard formats and protocols such as MIME and HTTP are supported. It includes modules for creating graphical user interfaces, connecting to relational databases, generating pseudorandom numbers, arithmetic with arbitrary-precision decimals, manipulating regular expressions, web scraping, test processing and unit testing. You can use Python to make web apps with the help of frameworks like Django, Flask etc. There are many job roles like software engineer, web developer, data engineer, automation engineer, data scientist, data analyst that require proficiency in Python.

Learning Python opens up plethora of options for data science fields like Artificial Intelligence (AI), Neural Networks (NN), Machine Learning (ML), Data Analysis, Data Processing, Data Visualization etc as it contains numerous libraries and frameworks built dedicated for these purposes. Python has powerful improvements related to asynchronous operations i.e., websites made of Python can handle thousands of requests each second. This is the reason why popular websites you use everyday like Google, Facebook, YouTube and Quora use Python. The streaming service Netflix heavily relies on Python for security automation and training its machine learning models used for making its recommendation algorithms. Instagram, a photo sharing service with 400 million daily active users sharing more than 95 million photos and videos recently shifted its framework to Python. Spotify, the world's most popular music streaming service with 320 million users is 80% made of Python. These services use Python for various purposes like image processing, data analysis, machine learning, big data, speed, scalability etc.
