To learn how you can move ahead with Web Development in Python, it is important to know a few things first, like web frameworks, frameworks in Python, Python libraries, etc. You can also learn more about these topics if you sign up for a Python Training in Bangalore. Here, we will take a brief look at what web development in Python entails.

Web Framework – Overview

A web framework is a package of resources, tools, and modules that are used by Web Developers to build and manage web applications, websites, and web services. These frameworks pack templating capabilities that allow a programming environment for scripting the flow of information, presentation of information within a browser, and APIs that allow access to underlying data resources.

In addition to the foundations, the web framework also includes system-level services for the developers to develop a content management system (CMS). The CMS is used for the management of information on the web. The frameworks are also used to define the administrative tools, user authentication features, and other atypical content management capabilities. 

Web frameworks can be built upon a pre-defined infrastructure like Linux, Apache, MySQL, and PHP, otherwise known as the LAMP stack. Once the web framework is defined and implemented, it is difficult to modify the core CMS capabilities.

Python Web Framework

It is possible to build a web application from scratch using Python. Here are the five reasons you should choose a Python web framework:

• Trusted by Many Multinational Organizations

Giants like Instagram, Pinterest, Dropbox, Bitbucket, etc. have used well-known Python frameworks such as Django and Pyramid for the creation of web applications. So, it is pretty much evident that these systems are capable of handling a lot more than you may expect.

• Hides Complex Low-level Information

Web frameworks work in a way that they cover and maintain all low-level information. This makes it easier for developers to develop a web-enabled program without having the need to deep dive into how everything operates.

• Saves Time And Energy

Using a Python web framework saves time and energy as the architectures are developed in such a way that it commits thousands of developers and test hours. It is safer to use Python frameworks because of this, especially when one is building a prototype of a basic website or is nearing a deadline.

• Security

Using a Python web framework is more secure than creating anything on your own. Web applications are better protected as the web frameworks have been implemented and backed up by thousands who are also implicitly responsible for protecting them.

• Flexibility and Scalability 

Good mechanisms are set in place in Python web frameworks to accommodate scalability from the very start of the production process. 

Which Python Framework to choose?

While there are several Python web frameworks to choose from (each with its own strengths and limitations), one should consider the project specifications and make the choice. Any Python Tutorial online will give you all the information that you need to know to decide on the right framework for your project, but the following are three of the most popular web frameworks suitable for use with Python.

Django

Django is the most widely-used Python web framework that targets a wide range of applications. It has everything that is required for web development that works well together with the system itself. For example, database management, authentication, routing, prototype, etc. are all taken care of. With knowledge in Python, one can create a mid-high range of site applications using Django.

Pyramid

If you are looking for a very versatile Python web framework, then Pyramid is the one you are looking for. It is used for mid-scale applications and provides a plug-in framework as per the project specifications. It includes simple site development features like authentication and routing. 

Flask

Flask is a new microframework that is targeted at small-scale applications. It has useful features incorporated from other frameworks. Some of the features include built-in development servers and unit testing that enables the development of functional and stable web applications.

Python Libraries

Here are a few handy Python libraries that are used in web development:

• Scrapy – A web crawler used to retrieve data from your application, processing, scraping, data automated research, etc.
• Zappa – Used for creating an AWS Lambda serverless program
• Requests – Enables quick submission of HTTP requests and connect with an application
• Dash –  Helps create web apps associated with data visualization and provides visuals, maps, dashboards, etc.

A Guide to Web Development in Python

Following is a brief guide for web development in Python:

Step 1: Web Page Design

• HTML: Every Web Developer is expected to know the fundamentals of HTML and browser definitions, hosting, DNS, and HTTP request and response.

• CSS: CSS specifies how HTML elements look on a web page and entails a website’s design, and formatting, and presentation, etc. Examples of CSS frameworks are Bootstrap and Materialize.

Step 2: Webpage Behaviour

• JavaScript: Once the website is built, the behavior of the pages should be monitored. To do this, JavaScript is necessary. The source code will contain a range of  HTML, CSS, and JavaScript code that was written for the web page.

Step 3: DOM Direction 

• jQuery: jQuery is the most common JavaScript library that provides effective methods for the purpose of DOM infiltration. There is no need for massive codes for adjusting the value of an entity attribute or removing an HTML code from a section. It provides methods to extract details from DOM components for future use. The DOM section can be uninstalled, inserted, or substituted with the help of jQuery. 

Step 4: Front End Framework

Knowing about front-end frameworks is just as important as it helps understand full-stack growth.  Angular, Ember, Vue, Backbone, and React are a few examples of frontend frameworks.

Step 5: Programming Language

Python comes with a number of IDEs like Jupyter Notebook and Pycharm that make writing Python codes simple and user-friendly. Aside from Python, there are several other programming languages that can be used.

Step 6: Web Framework

One can choose from python web frameworks like Django, Flask, Pyramid, etc. To be able to handle the business information utilizing frameworks, one must be knowledgeable about the fundamentals of databases like MongoDB and SQLite.

Conclusion

If you want to finish a web development project with fewer lines of code, then Python frameworks are your best bet. It is the go-to solution for developers around the world. It’s best to start with one framework first rather than trying to master all of them at once.
