how to create web browser Using python

Hello coder, welcome to the codewithrandom blog. In this blog, we will Create a Web Browser Using Python. Creating a web browser can be a challenging task, but it’s an excellent way to improve your programming skills. In this blog post, we’ll explore the steps involved in creating a web browser in Python.

What is web browser  ??

A web browser is a software application that allows users to access and navigate the World Wide Web (WWW) or internet. The web browser has become an essential tool for accessing and interacting with various web-based applications, services, and content on the internet. Example : — Some of the popular web browsers include Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Opera.

Web Browser Features:

Home Button: This button must-have capability to take the user directly to the home page.
Forward Button: This button will take the user to the next site.
Back Button: This button will take the user to previously visited websites.
Reload Button: It will have the capability to refresh the content of the site.

Prerequisites:

Before we start building Web Browser , you should have a basic understanding of Python and the following libraries:

PyQt5 :  PyQt5 is cross-platform GUI toolkit, a set of python bindings for Qt v5.

PyQtWebEngine : The framework provides the ability to embed web content in applications and is based on the Chrome browser.

You can install these libraries using pip, a package manager for Python, by running the following command in your terminal:

$ pip install PyQt5
$ pip install PyQtWebEngine

# Importing required modules:
import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebEngineWidgets import*
#Functions definition and creation of classes:
class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow,self).__init__()
        self.browser = QWebEngineView()
        self.browser.setUrl(QUrl("https://google.com"))
        self.setCentralWidget(self.browser)
        self.showMaximized()
# Coding for buttons and their functionalities:
        #navbar
        navbar = QToolBar()
        self.addToolBar(navbar)

        back_btn= QAction('Back',self)
        back_btn.triggered.connect(self.browser.back)
        navbar.addAction(back_btn)

        forward_btn = QAction('Forward',self)
        forward_btn.triggered.connect(self.browser.forward)
        navbar.addAction(forward_btn)

        reload_btn = QAction('Reload',self)
        reload_btn.triggered.connect(self.browser.reload)
        navbar.addAction(reload_btn)

        home_btn= QAction('Home',self)
        home_btn.triggered.connect(self.navigate_home)
        navbar.addAction(home_btn)

        self.url_bar=QLineEdit()
        self.url_bar.returnPressed.connect(self.navigate_to_url)
        navbar.addWidget(self.url_bar)

        self.browser.urlChanged.connect(self.update_url)
         
    def navigate_home(self):
        self.browser.seturl(QUrl("https://google.com"))

    def navigate_to_url(self):
        url=self.url_bar.text()
        self.browser.setUrl(QUrl(url))

    def update_url(self,q):
        self.url_bar.setText(q.toString())

app=QApplication(sys.argv)
QApplication.setApplicationDisplayName('CodeWithRandom browser')

window = MainWindow()
app.exec_()
