How to Create a Web Browser with Python and PyQT

Enough of browsing, let’s create a browser with python

In today’s world, almost everyone is using the internet. To access the world wide web we need a browser.

In this article, we will be creating a simple web browser with python and PyQT5.

PyQT is a widely used module which is used to make GUI applications with much ease. We can develop many complex GUI applications using PyQT very easily. It has a modern look and light user interface. Even if you are not familiar with this module, you will be able to create a web browser as each and every line is explained in the code itself using comments.

We often confused between the terms web browser and search engine, so let’s quickly have a look at these two terms.

Search Engine: It is used to search the required information from the World Wide Web using a web browser. It actually allows us to search the internet.

Web Browser: It is used to access the World Wide Web / Internet.

Now, you might have a clear picture of the mentioned terms. We can use any search engine, so we will be using Google search engine in our project.

Python Web Browser Output

python browser home

browser load website


We have successfully created a web browser using python and pyqt5. Now you are familiar with another python’s GUI module (apart from tkinter).

We have explained the code using the comments in the code itself but still if you have any doubts. You may ask in the comment section.

Happy Coding !!!
