Stepwise Guide to Web Development with Python

So, you wrote the Python script now that you feel great. Do you want to show it to the world? But how can you do such a thing? Many people are not aware of what the .py file is all about. So, the python web application is the best solution to make the code used for the audience.

A closer look at the Python frameworks

Web Frameworks are extensive libraries and pre-built code collections that help to speed up the web development process. By accessing the web framework, you access the features and tools to create a web application in Python easier. 

This provides an accessible framework and flexibility to the new developers to build the website application using a single Python file. Besides that, it is extensible and doesn't force directory structure before getting started. 

The best part is you can create the best codes even from scratch. For example, some of the popular web development frameworks are as follows:

Django

For an uncluttered web designing process and development features, Django is the best framework for you. With Django, you will access all the essential web components like database integration, admin capabilities, and some authentication features. This is one of the secured Python web development tools that operate on the app-based concept without external dependencies. 

Flask

Flask is another minimalistic framework that is helpful for web development. Although it lacks certain features such as authorization capabilities and authentication, it still allows you to design the website. 

It gives you the bare minimum, which is highly recommended to build your website and allows you to process the data. 

Apart from these two frameworks, you can use other frameworks such as: 

  • Bottle
  • Pyramid
  • TurboGears

But the question is, which framework do you choose for web development? Well, it depends on your programming skills. But if you're a newbie that desires Django and Flask, no matter what framework you choose, the foremost thing is to start coding. 

Stepwise guide to web development with Python

As you understand the prime components needed for web development, the next step is to put them all together and follow the stepwise guide to web development with Python. 

Step 1. (Get a grip on CSS and HTML)

For any website developer worth their knowledge, having a grip on CSS and HTML is a must. These two programming languages act as the backbone of the website development process. Without these programming languages, the developer cannot create the front-end, which the part of the website helps to be visible in the browser. 

Step 2. (Learn the basics of JavaScript)

The basics of JavaScript are essential to creating the best client-side program scripting language without which no website can run smoother. In addition, it helps to make the most powerful elements such as client-side animations, validations and many more. 

Step 3. (Learn about document object model)

Once you have done the basics of JavaScript, this is high time to learn about the Document Object Model, which you can use to create dynamic web pages. It is also beneficial to learn about jQuery, the JavaScript library that simplifies DOM working. 

Step 4. (Think about backend development with Python)

After learning the above step, you will be all set for Backend Development. Here comes the front part, where you use Python to create the backend. This is the main part of the website code that specifically runs on the web server. 

You can start by learning the Python syntax and then shift to learn about the framework like Flask and Django. After understanding all the basics of JavaScript, everything, including Python, seems to be a breeze. 

Steps to follow to build a web application using Python

Follow these steps to make the website application using Python.

Step 1: Create an empty file

The first step to web development using Python is to create an empty file and save it into the .extension format with adequate codes. After completing the empty file, you get to know that the code will employ the framework if you notice any command.

Step 2: Installing flask

First, you need to activate or install the flask Python environment. However, if you do not have an activated programming environment, ensure your project directory and follow the commands to start the environment. Once your Python programming environment is activated, you now have an env prefix. 

After that, you can isolate the project code away from the prime Python system installation.

Step 3: Create the base of the application

Now, as you set up your Python environment, you can start using flask. In the second step, you'll create a small website application into the Python file and access it to start the server. When you start, this will display some information. 

Open the file name for editing. This file will serve as a mini example of how you can handle HTTP requests. First, import all the flask objects, and then create functions for the HTTP response. 

Step 4: Use HTML templates

At present, your raw application will be displayed like a simple message without any form of HTML. However, keep in mind that web applications use HTML to display the information, so you need to use the HTML files within your app to be displayed on a web browser. 

Step 5: Set up the database

In the fourth step, you need to set up the database to store the whole data. You can also access the SQLite database file if you want to store the data because the SQLite 3 module, which you use to interact with the database, is hardly available in the Python library. You can store the data in the table and even column form. 

Step 6: Display all the posts

After setting up the database, you need to modify the index (). Then, view all the functions to display the stored posts in your database. For this, Open the app-py file and follow all the modifications needed. 

Import the SQLite 3 module to the top of the file. 

Step 7: Display the single post

You need to create the new flask route and a new HTML template on an individual blog in the sixth step. At the end of the step, you will get a URL which will be displayed on the first post. 

Open the app-py for editing and add new blog posts by its ID pick from the database or multiple locations. After completing the steps, you get the link to the top of the index page, expected as functional.

Now, you can finish the building part of the website application, responsible for displaying the blog post into the database. Last, you need to modify the post, and your web application is ready. 

Conclusion

So, here you go with website application building using Python and flask. You can also take the local Python script to design the website applications. Now, that you know how you can build your first web app using Python, kick out of the box and start creating your web application.
