How to build a web application for python

Creating a web application using Python can be accomplished with the help of various frameworks. One of the popular frameworks is Flask, which is a lightweight web application framework. In this tutorial, we will build a simple web application using Flask. Ensure that you have Python installed on your system. If not, you can download it from the official Python website.
Use the following command to install Flask using pip, the Python package installer:
Create a new directory for your project and navigate into it. Inside this directory, create a Python script, for example, app.py.
Add the following code to app.py:
Run the following command in your terminal:
Now, open your web browser and go to http://127.0.0.1:5000/ or http://localhost:5000/. You should see 'Hello, World!' displayed on the screen.
Let's add another route to the application. Modify app.py with the following code:
Create a folder named templates in your project directory. Inside the templates folder, create a new HTML file named index.html.
Add the following content to index.html:
Now, modify app.py to render this template:
Run the application with the command:
Access http://127.0.0.1:5000/ in your browser to see the updated home page.
Congratulations! You have successfully created a simple web application using Flask. You can now build upon this foundation by adding more features and enhancing the functionality of your web application.
