Over the past couple of decades, Python has exploded in popularity. Its programming language now surpassed Java in popularity, however for a lot of people users, this comes as no surprise.
With the rapid growth of the field of machine learning and data analytics and the development of web-based applications numerous developers are using Python due to its speedy and numerous libraries, its easy-to-learn syntax, and its portability.
It's an ideal time to be a Python developer. Today, you'll be able to be able to understand how Python can be used to develop web applications.
Web Development is What It Sounds Like?
Those who are new to programming may be asking themselves what web development means. While it's hard to pinpoint the exact meaning of the term web development can be loosely defined as the process of creating, building and maintaining websites.
The majority of web development projects involve a frontend, which is everything that communicates with the client as well as a backend that contains business logic and communicates with databases.
What is It That Makes Python Best Suited to Web Development?
The advantages of developing web-based applications using Python
It is easy to master: Python is the most well-known language for beginners because of the reason. The language is built on familiar expressions and whitespace. This lets you write less code than other languages such as Java as well as C++. Additionally, it is less difficult to learn entry since it's closer to your daily language, which means you'll be able to learn the code.
A rich library and ecosystem: Python offers a vast array of library tools and programs that allow you to utilize a large amount of already-written code, which can speed up the development process of your app.
For instance, you can use Numpy as well as Pandas for the analysis of mathematical data, Pygal for charting, and SLQALchemy for customizable queries. Python also has amazing web frameworks, such as Django and Flask that we'll get into later in this article.
Prototyping speedy: Since Python is significantly faster to create your projects in comparison to other programming languages, you can see your plans become reality quicker, which allows you to gather feedback and improve your designs rapidly.
This speedy development time makes Python particularly suitable for startups, who can hit the market faster to get an edge over competitors.
Popularity widely spread: Python is one of the most used languages around the world and has communities across the globe. Due to its popularity is Python constantly updated to include new libraries and features and also provides excellent documentation and support for community members.
Particularly for new developers, Python provides extensive support and a framework to begin their development journey.
Python web frameworks
What exactly are Web Frameworks and why are they important?
Imagine a toolbox. Web frameworks are collections of modules and packages composed of pre-written standardized code that facilitates the development of web-based apps that make development quicker and more efficient, as well as your applications more stable and flexible. Frameworks already come with components built-in to "set up" your project and you need to perform less work.
Python web frameworks are employed in the backend to support server-side technologies, which aid the process of URL routing HTTP request and responses as well as accessing databases and security on the web.
Although it's not mandatory to utilize web frameworks. However, it is highly recommended as it will help you build complex applications in a shorter time.
Note: If you reside in Surat and are interested in pursuing offline courses, DecodeX Infotech offers a Web Development Company in Surat, where you can learn web development and enhance your skills.
What Are Some of the Most Well-known Python Web-based Frameworks?
Django as well as Flask are by far the most well-known Python Web development frameworks
Django is a Python web framework that provides an open-source, advanced framework which "encourages rapid development and clean, pragmatic design." It's quick, secure and expandable. Django has strong community-based assistance and extensive documentation.
Django is incredibly flexible, in the way that it can be used to collaborate alongside MVPs to larger corporations. To give an overview Some of the biggest companies using Django include Instagram, Dropbox, Pinterest and Spotify.
Flask is often referred to as a micro-framework. It is a simple web framework. It's less "batteries-included," meaning that it lacks a lot of features and functionality that full-stack frameworks like Django offer, such as a web template engine, account authorization, and authentication.
Flask is lightweight and minimalistic it allows you to develop extensions and add libraries you require as you write without being automatically included through the framework.
The basic idea that drives Flask is to ensure that the application provides only the necessary components to create an app, to give you the ability to control and flexibility.
Flask also is a popular and powerful web framework, as it is used by major corporations such as Netflix, Linkedin, and Uber.
Which is the Best Option?
You might then think: which framework should I pick? The answer is it will depend on your needs. Take into consideration your level of expertise as a web developer. If you're experienced you can think about creating your program using something that is more "barebones."
For novice developers, it may be more beneficial to choose an application framework that offers more assistance like Django.
Ask yourself: do you prefer a "foundation" codebase to build on or allow you to use it to construct the core of your codebase? If you would prefer the first option, then go with Django and if you're more interested in the alternative, choose Flask.
In the final analysis, they'll each achieve the same function and it's important to get started coding instead of worrying about which one is the best.
Python Libraries to Help With Web Development
A few helpful Python tools for developing websites. Take on your radar:
If you're ever in need of an internet crawler that can extract information for your application, then Scrapy is a great choice. It's a well-known tool for scraping as well as automatized testing, data mining and much more.
Zappa is a robust library that allows you to create applications that run serverless using AWS Lambda.
Request is a program that lets you send HTTP requests quickly, which can be used to connect with an application. It allows you to receive HTML pages or other data such as.
Another helpful library is Dash which aids in designing web applications with to do with visualization of data. Based on Flask Dash offers functions such as graphs, charts, dashboards, and so on.
The Roadmap to Web Development Using Python
Step 1: HTML + CSS
If you're just beginning in the field of the development of websites, it's crucial that you begin by learning HTML and CSS as they are the basic elements of developing websites.
It's best if you could structure dynamic static pages that are responsive before you begin your journey of web development. It may also be helpful to master concepts like the Internet, HTTP, browsers, DNS hosting, DNS, and many more.
It is also possible to learn a CSS framework such as Materialize or Bootstrap which can speed the process of development, but it's not required.
Step 2: Javascript
The next best thing to do is to study the basics of Javascript. It is essential to understand the basics such as data types, variables' general rules, string manipulation operators and arithmetic, loops, control statements, and so on. Knowing the basics of Javascript makes it simpler for you when it comes to applying Javascript to client-side code.
Step 3: DOM & jQuery
When you've learned javascript basics, you must master manipulating your DOM and jQuery is a javascript library that helps to make DOM manipulation much easier. You now can build dynamic web pages.
Frontend Framework (optional)
Although it's not necessary to master a front-end framework like React to create a fully functioning full-stack website application It is strongly recommended. It's not only helpful in helping in creating beautiful SPAs however, it's frequently a requirement for being employed as a frontend as well as a full stack developer.
Step 4: Python
Then, let's move on to the backend. It is important to learn the fundamentals of Python similar to what you learned for Javascript prior to beginning to learn DOM manipulation. Understanding the basics will help you prepare for Django and you won't feel as frightened jumping into the water. Beginning to learn Python should not be difficult, however, since some of the concepts are identical to Javascript.
Step 5: Django + Database
With Django, it is possible to establish your backend environment and create an enterprise logic. Additionally, you'll need to understand databases like SQLite and how to create queries, as well as the CRUD function. This will allow you to build a full-stack app!
