Python for Web Development

Introduction

Since the beginning of the decade, Python has been gaining popularity. The popularity of the programming language has eclipsed that of Java, but this shouldn’t surprise anyone. Due to its powerful and plentiful libraries, easy-to-learn syntax, and portability, Python is popular in fields such as machine learning, data analysis, and web development.

Being a Python developer at this time is an awesome experience. The article will demonstrate how Python is used in web development.

Web Development – What Is It?

Developing applications for web browsers is called Web Development, although it is an extremely broad field. There are two components to a web application: the frontend and the backend.

Frontend

User interfaces provide users with access to and control over the features of web applications. When a user accesses a URL for a particular web application, it appears in the URL field of the user’s web browser. Application frontend developers are typically responsible for managing interactions with the web server, retrieving and displaying data, and saving or manipulating it as it occurs. The person who manages the interaction with the web server handles tweets, blog posts, and other content sent to it.

Backend

In web applications, the backend is responsible for server-side handling aspects. Here is where Python shines when it comes to Web Development. In order to store, retrieve, and format data in an agreeable format compatible with other applications, the backend handles the storage, retrieval, and formatting of the data. Because the data is exchanged via HTTP on a web server, the backend of a web application must be capable of parsing HTTP requests, understanding the HTTP request’s content, and acting accordingly on the data received from the HTTP request. It is possible to store, validate, update, delete, and retrieve data by means of these operations, as well as many others.

A multitude of ways can be used to develop applications based on these two aspects. There are a number of ways to go about this, one of which is to do everything on the server. As an example, a web page’s frontend, such as HTML, CSS, and JavaScript, might be stored on a server, templates would be created and filled with data from a database, the entire web page would be constructed on the server, and the code would be sent to the browser. Smaller web applications can get away with this, but this may slow down larger applications.

The frontend parses and displays the templates and data returned from the server using the server-returned data. The frontend developer uses JavaScript to accomplish this task, speeds up the entire process, and frees up server-side processing.

Why Is Python a Good Choice for Web Development?

As a result of Python’s versatility, user-friendliness, and some unique features, it is ideal for developing web applications, as we will demonstrate in this blog. We will now discuss Python’s use in developing web applications.

The Curve of Learning Is Short

Python’s popularity is due to its ease of learning. In addition to being clear and concise, Python was designed to be easy to learn and use. Several factors contribute to its readability, including its syntax. Rather than relying on convention, it emphasizes clarity. Unlike Java, C#, or C, Python requires less code to accomplish something similar, mainly due to its different syntax from other programming languages. Other languages, such as Java and C, use symbols and words, such as “&&” and “!” That makes other languages less readable and difficult to learn. Python, on the other hand, uses indentation and natural English-like words, such as “and” and “null,” making other languages more difficult to read and learn.

An Ecosystem of Richness

It is common for developers to encounter some challenges when developing applications. They must perform more than just data validation. In addition to reading CSV files and making network requests, data from CSV files must also be collected. There is a lot of repetition in these tasks as well as common tasks. Code bundling can be used by developers to simplify complex tasks. Other developers who are trying to solve similar problems will be able to use these libraries if they distribute them on the internet.

A wide range of libraries is provided by Python, which allows developers to solve a variety of problems. Libraries can also be distributed by developers to other developers. This allows developers to focus on developing applications and solving problems unique to their field rather than addressing issues that have already been addressed.

Speed of Development

Python is an easy-to-learn and easy-to-use programming language which accelerates development significantly. Since Python is already packed with a lot of libraries, developers are able to spend more time developing applications as a result. As well as enhancing the speed of development, Python’s syntax and tooling make it easier to code. One of the major reasons why Python has become so popular has been the advantage it has in terms of speed of development.

It is not suitable for the development of certain kinds of applications, such as graphics software and device drivers, since Python is an interpreted high-level language and is slower than low-level languages like C, C, and so forth. Software application development speed is still more important than variation in execution speed for most applications. There are many fields in which Python is used, and it has gained popularity.

An Extensive Community

Due to its wide acceptance, Python has a large developer community. The community has been using Python for quite some time and has a great deal of experience with it. As a result of such a large developer community, Python is an easy language to learn web development because you can get assistance from other developers with any questions that you might have. There are also a vast number of developers willing to help developers resolve the problems that they face when developing applications.

Frameworks for Python Web Development

How and why should you use web frameworks?

Consider a toolbox. Due to the prewritten, standardized code in web frameworks, app development can be done more quickly and easily. Furthermore, these frameworks improve the reliability and scalability of the software, as well as the reliability of programs. As a result, you spend less time on grunt work because frameworks already have components built in.

HTTP requests and responses, databases, URL routing, and security are all handled on the server side of Python web frameworks. Using a web framework is not a requirement, but it is highly recommended because it speeds up the process of developing complex applications.

Python Web Frameworks: What Are Some of the Most Popular Ones?

Among Python web development frameworks, Django and Flask are the most popular.

Django is a Python framework that is open-source and high-level, which allows you to build fast, secure, and scalable web applications. With this framework, you are encouraged to develop quickly and to use clean, pragmatic designs. The documentation and community support offered by Django are excellent.

There are countless possibilities when it comes to using Django, from MLPs vs MVPs to large companies. Spotify, Dropbox, Instagram, and Pinterest are among the largest businesses that use Django.

A microframework, Flask is a minimalistic framework designed specifically for web development. In comparison to full-stack frameworks like Django, this framework offers fewer features, such as generating web templates and validating customers.

Flask is minimalistic and lightweight, meaning that you add extensions and libraries that you need as you code without automatically being provided by the framework. By providing only the components for building an app, Flask enables flexibility and control. Many large companies, such as Netflix, Linkedin, and Uber, use Flask as a web framework.

Web Development With Python Libraries

Here are some Python libraries you should keep in mind for web development:

• A web crawler like Scrapy can make it easier for your application to extract data from the web. In addition to scraping, data mining, and automated testing, this library is capable of performing a wide range of tasks.

• AWS Lambda support is provided by Zappa, which is a powerful library for building serverless applications. Consider a Python Boto3 tutorial to help you to solve automation problems related to Python programming language in Amazon Web Services.

• HTML pages or data can be sent to an application using HTTP requests, for example, for convenience, so that you can communicate with it.

• The Dash library is also one of the most useful libraries for those who develop web applications that make use of data visualizations and have to work with data. Based on Flask, the library provides a range of features such as charts, graphs, dashboards, and more to make it a powerful tool.
