Python and it’s powerful libraries

6 min readAug 14, 2020

I think there is no one who did not hear the term Python in tech field. As python is the fastest growing language in term of developers, libraries and applications it can be used for.It could be Web development, Machine learning, Artificial Intelligence or anything you can think of, python got you covered.

What is Python?

Python is a general purpose programming language,which is high-level,interpreted with easy syntax & dynamic semantics and has a large and powerful module libraries.Python was created by Guido Van Rossum and released in 1991.

Every language have it’s own way to describe the blocks of code.Many languages use curly braces to describe the blocks of code but instead of curly braces python uses indentation to describe the blocks of code.

In start,it doesn’t receive too much attention as it’s slow compared to other languages.But with the rise of Artificial intelligence and Machine learning, Python comes into spotlight because it makes the work much more productive and much more easy.As now we have the amazing computing power so we want to be more productive no matter it takes a little more time.

Why Python is so popular?

Python is really popular in recent years.Worldwide, Python is the most popular language, Python grew the most in the last 5 years (20.1%).Here are some reasons why it’s popularity increases so much in recent years-

Easy and High-level—

Python has high level features and easy syntax which makes it best for everybody to get started with programming.It is the language for everybody.

Free and Open-source —

Python is an open-source language which means we can use it for free and also contribute by programming to make it more easier and powerful.There are millions of programmers who contribute daily to make python better.So you can modify the code ,break the code & make the code without any problems.

Applications —

Python is a language using which you can develop any type of applications such as GUI applications,Web applications,Artificial intelligence,Mobile apps,server-side applications,Machine learning,Algorithms and many more.So any application you want to make ,python can help you with it’s easy syntax and powerful libraries.

Libraries & Support —

Python has a great community who constantly make libraries and help those in need.For example Machine learning algorithms are already available to makes you code better,to right up your productivity and to make your code easier.

Features of Python

As we all know every language have it’s special functionalities or features which makes that language different from others.Python also have some features which makes python different from others languages.

Simplicity —

Python is very simple and easy to read programming language.Due to it’s simple and easy syntax anyone who want to start programming from scratch can start programming with python easily and efficiently.

Open-Source —

It is an open-source programming language which means free to use for everybody.

Portability —

It also have portability,Write your code and share with anyone you want to share,it will work in the same way as before when you run the code.

Embeddable & Extensible —

Python is embeddable as we can use python in application easily.Python is extensible as python supports adding code of different programming languages like C,C++,Java etc. to itself to run different functions,which makes it more powerful.

Interpreted —

Python is an interpreted language means it uses an interpreter.An interpreter executes the statements of code one-by-one or line-by-line.So it is helpful in managing the CPU and memory.It also makes debugging easier.

Huge-libraries support —

I think the best and the most powerful feature of python is it’s huge libraries support.Which makes it very easy for everyone to program and to do a lot of things with python by using these libraries.You just have to import that module or library into your program and you are able to use all of its features and functions.

OOPs —

Python allows Object oriented programming by which we can model real life problem into our code and add security like access restriction and others.We can use objects, class, inheritance, polymorphism, abstraction, encapsulation and other OOPs concepts to model real life problems into code.

How to start learning Python?

There is a question in mind of every beginner that where do I start programming.So there is learning path you can follow to learn python easily and sequentially.

Start with variables ,different data types and operations like addition, subtraction and others.
Arrays are used to store data in structured manner.Learn how to use arrays and other in-built data structures like list,dictionary,tuple,sets.
Flow control means learning about loops,conditions like how to use them,where to use them etc.
Methods are the functions which belong to an object,like list objects have methods like append,insert ,remove etc.
File handling means working with files like how to open a file ,closing a file ,adding contents etc.
Object oriented programming(OOPs) is a very important concept in programming.It has objects,classes,Inheritance,polymorphism, abstraction and some other concepts to learn.
And keep practicing that will make you an expert in programing.

After learning of the basics start learning advanced concepts in python like advanced functions(like map,filter,reduce,zip etc.),lambda functions,list comprehensions,Modules and there are also some popular modules for a particular field as for Machine learning we have Pandas, TensorFlow, keras, Pytorch,numpy etc., for web scraping we have Beautiful Soup, Requests, Scrapy ,LXML and others.

You can learn python using books,online articles,youtube tutorials and other platforms.If you have any difficulty in learning python by self , you can also take mentor support through online or classroom courses.

Career opportunities with Python

So there are a lot of opportunities for a python developer , there are multiple fields in which you can make your career and improve yourself.

Web development —

Web development with python becomes popular using frameworks. Python offers many frameworks from which to choose from including bottle.py, Flask, CherryPy, Pyramid, Django and web2py.These frameworks have been used to power some of the world’s most popular sites such as Spotify, Mozilla, Reddit, the Washington Post ,Yelp etc.

Game development —

Game development can be done with python using PyGame.PyGame is a set of Python modules designed for writing games. This allows you to create fully featured games and multimedia programs in the python language.There are also other frameworks available like PyKyra, Pyglet, PyOpenGL, Kivy etc. to develop games with python.Battlefield 2 game uses Python for all of its add-ons and a lot of its functionality.Another game Civilization IV uses Python for most of its tasks.

Machine learning—

Machine learning is one of the most popular career option now a days. Machine learning can be done with python.Python has so many libraries for machine learning like Numpy, Scipy, Scikit-learn, Theano, TensorFlow, Keras, PyTorch, Pandas, Matplotlib etc.According to a report from job site Indeed, machine learning engineer is the best job of 2019 due to growing demand and high salaries.

Web testing —

Web testing is also a career option for a python user.There are Selenium, Appium Python, Katalon studio and other libraries available for web testing.

Data Scientist —

Data scientist, it is one of the most popular word in the field of python development.Python has different libraries for different data operations.For Data mining we have Scrapy, Beautiful soup ,for Data processing and modeling we have NumPy, SciPy, Pandas, Keras ,TensorFlow, PyTorch etc.,for Data visualization we have Matplotlib, Seaborn and other libraries available.So choose your interest and start learning according to the job you want.

Smart devices —

IoT(The Internet of things) is a big deal today.IoT development is rapidly growing as we are going deep in the field of technology.Python can be used as a scripting language in IoT development. IoT, when integrated with AI, will help developers to work with Python further.

So in the end we can say that python can do anything you want to do with it. Python gives you the tools to work anywhere in the tech field.
