Build your own web browser using python

To build your own web browser using Python, you will need to use a few libraries. Some options you can use include:

• PyQt5: This is a set of Python bindings for the Qt application framework and is available under the GPL. You can use it to create a graphical user interface (GUI) for your web browser.
• PyGTK: This is a set of Python bindings for the GTK+ widget toolkit. It can be used to create a GUI for your web browser.
• PySide: This is a set of Python bindings for the Qt application framework. It is available under the LGPL and can be used to create a GUI for your web browser.

You will also need to use a library to handle the web browsing functionality itself. Some options you can use include:

• web browser: This is a built-in Python library that provides a high-level interface to allow displaying Web-based documents to users. It can be used to open a web page in the default web browser or a new browser window.
• mechanize: This is a library that provides a set of convenient functions for interacting with websites via programmatic means. It can be used to simulate a web browser and perform actions such as filling out forms and clicking links.

Once you have chosen the libraries you want to use, you can use Python to create a GUI for your web browser and handle the web browsing functionality. You can start by creating a simple GUI with a text field for entering a URL and a button for navigating to that URL. You can then use the web browsing library of your choice to handle the actual navigation.

Here Is a example code to build web browser using the python pyQt5 library

import sys
#pip install PyQt
from PyQt5.QtCore import QUrl
#pip install PyQtWebEngine
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage
from PyQt5.QtWidgets import QApplication, QLineEdit, QPushButton, QVBoxLayout, QWidget

class Browser(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()
    
    def initUI(self):
        self.setWindowTitle('Web Browser')
        self.setGeometry(100, 100, 800, 600)
        
        self.url_field = QLineEdit(self)
        self.go_button = QPushButton('Go', self)
        self.go_button.clicked.connect(self.navigate_to_url)
        
        self.view = QWebEngineView(self)
        
        layout = QVBoxLayout(self)
        layout.addWidget(self.url_field)
        layout.addWidget(self.go_button)
        layout.addWidget(self.view)
        
        self.show()
    
    def navigate_to_url(self):
        url = self.url_field.text()
        if not url.startswith('http'):
            url = 'http://' + url
        self.view.setUrl(QUrl(url))

app = QApplication(sys.argv)
browser = Browser()
sys.exit(app.exec_())
