Say Goodbye to Chrome: Build Your Own Browser with PyQt5 and Python

Alright folks! Let's build a browser so unique and wild that even Chrome would be envious! We'll be using Python and PyQt5 to build this browser, so make sure you have both installed on your computer. If not, you can use the following command to install them:

pip install pyqt5
pip install PyQtWebEngine

Now that we have the necessary tools, let's get into the code. The full code for this project can be found on this GitHub repository: https://github.com/Pandeyashish17/browser-using-python. Not only the code but also all the button images that we will be using in this project are available there.

We're using PyQt5 to create a QTabWidget and a QMainWindow, which will serve as the foundation for our browser. We're also using PyQtWebEngine to create a QWebEngineView, which will be used to display web pages.

We're creating a bunch of buttons with images like 'back.svg', 'forward.svg', 'reload.svg', 'home.svg', 'add.svg' which are available at the repository mentioned above. These buttons will have different functionality like back, forward, reload and navigate home.

We're also creating a search bar, which uses Google to search for whatever you type in. So, whether you're looking for funny cat videos or researching the latest and greatest Python libraries, our browser's got you covered!

app.exec_()

Now, let's run the code and see our wild and unique browser in action! You can easily customize the browser as per your need and create something even more unique and wild.

And there you have it, folks! Your very own, one-of-a-kind browser built with PyQt5 and Python. Now you can surf the web in style, with all the fun buttons and icons to make your browsing experience extra delightful. Happy coding!
