What Is Python Used for?
Created by Guido Van Rossum, python small learning curve, clear syntax, pretty indentation and thousand of open source libraries has made Python one of the best programming language for all level of developers. The high demand for python developers in the IT industry is also helping in the rapid growth of the python community. If you are new to Python, learning basics and wondering about What can I do with Python? or, what is python good for? or, what can python be used for?. So, here in this article, we have covered all the significant domains where Python is actually used, and we have also mentioned the python libraries or tools you need to master if you want to seek a career in a specific field. So, without further ado, let's discuss the significant domain where it is used. Domains where it can be used:- For web-development
- For IoT (Internet of Things)
- For Machine Learning
- For startups
- For Fintech.
1. Python in Web Development
Right now, every organization has a website that expands its reach on the online market and provides company existence over the internet. Creating, managing, and deploying a website or web-application comes under Web-development, and using the Python frameworks , we can create a robust and reliable web application for various devices. Web project that can be built using Python:- App for mobile and desktops.
- API's
- Responsive Web-applications.
- AI and ML-based Chatbots.
Top Python Web-Frameworks
A web-framework is a collection of libraries that is used to build dynamic web applications. However, we can create a web application using individual libraries, but web frameworks make it easier and faster. 1. Django Django is the most popular and widely used python framework. It is a full-stack web framework that comes with many built-in features such as admin authentication and verification. Django is highly recommended for big and medium-size projects, if you are building small projects like a to-do list or single page web applications, then Django would not be a great choice. Django also provides a built-in library for application testing, which is an extension of the python unit test library. 2. Flask Flask is the second-best python web-framework, but in some index rankings, it overcomes Django. If we compare Flask with Django, Flask is lean toward the small or micro size web-applications, and it often suggests to learn Flask before moving to Django. It is a micro web framework, and here we do not get built-in features like Django, but we can create all those features from scratch. Unlike Django, in Flask, we have to depend on other libraries and install some tools to build a high-quality web application. 3. Bottle The bottle is another light-weighted python web-framework that is widely used for learning and educational purposes. The bottle also does not offer too many built-in features, but it is mostly dependent on the Python standard libraries. It is an excellent framework for prototyping and building small and personal web applications. Here you do not need to worry about the nitty-gritty of various file creation while creating an app. 4. Pyramid The pyramid is a merger of two old python web-frameworks, Pylons and repose.bfg. And there was a time when pyramid was top python frameworks. In a direct comparison with Django, then pyramid has some significant advantages such as it is very easy to customize and build complex apps with ease.2. Python for IoT (Internet of Things)
IoT is one of the buzzwords of 2020, like Artificial Intelligence and Machine learning. If we want to define IoT in a nutshell, we can say that it is a concept about embedded physical objects which can connect with the internet for communication purposes. Now every IoT device comes with a unique IP address that allows it to communicate with the network. These days we can see a rise in IoT devices usages, and the time is not so far when every house will become a smart house and every office a smart office. IoT devices also play a vital role in cyber-systems, Machine Learning, and big data, with the help of wireless networks and sensors.Advantages
Generally, in IoT's we require those programming languages which are fast, light-weight, close to the hardware, and scalable. However, Python is neither quick or close to system hardware, but it still used in IoT because of its popularity, versatility and Raspberry Pi. 1. Python Libraries It has broad community support, and it has thousands of libraries. You name the IT domain, and Python has a library for it. With so many libraries present in Python arsenal, it's become effortless to use Python with anything. 2. System Independent It is portable and expendable, and its code can be run on any system or embedded devices. Right now, Python is supported by many operating systems and single-board computers which help python code to execute embedded systems. 3. Manage Complex data It comes with many built-in robust data structures that are capable of handling and organizing complex data collected by the system. 4. Easy to learn It is straightforward to learn basic Python, and that's one of the underlying reasons why Python is so popular. In Python, you do not need to worry about system formatting and compiling options python cover all and much more for you. 5. Easy syntax and less code It has a beautiful syntax which makes it's code more readable and clean. Python comes very handy for small devices where memory is limited, and we want to write the script with minimum lines of code. 6. Python with data science Currently, Python is widely used for data science and big data, because there are some data science and AI libraries which are only available for Python. Now data has become as valuable as money, and these smart IoT devices have become data collectors for big firms. So now they require such programming language in their IoT systems which can deal with the data flow. 7. Raspberry pi Raspberry pi is a popular microcontroller embedded device which is used for research and education purpose, and by default, it uses Python as its programming languages. 8. Easy Debugging It is an interpreted language that reads and executes code line by line, and if there is an error, the code execution stopped at the error line which makes debugging the program easy. 9. AWS support for Python AWS provides Python SDK for its devices, which helps python developers to write such scripts which allow them to access the AWS IoT devices.Tools for Python in IoT
1. Raspberry pi Raspberry pi is a small-single bord computer, widely used for teaching and research purposes of basic computer science in schools and colleges. It is highly portable and cheap, which makes it more popular among researchers and robotic developers. However, it does not come with any peripheral device like a monitor, keyboard, mouse, etc., but you can connect them separately to its USB and HTML ports. Raspberry pi is like a small and portable CPU that fits in your pocket. Raspberry has been used for many IoT projects because it comes with a Linux distro which makes it faster and more secure. Unlike other computers, system raspberry can run on little energy and support python as its default programming language. Projects that can build using Raspberry pi- Retro games.
