How to create your own Web Browser using Python and PyQt5

Here is a code of how you can create a simple web browser using Python and PyQt5, which will allow you to build an executable file:

import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWebEngineWidgets import *

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('Web Browser')
        self.setGeometry(100, 100, 800, 600)

        # Create a QWebEngineView widget and set it as the central widget
        # of the main window
        self.view = QWebEngineView(self)
        self.setCentralWidget(self.view)

        # Add a QLineEdit widget for entering URLs and a QPushButton
        # for loading the URL
        self.url_bar = QLineEdit(self)
        self.load_button = QPushButton('Load', self)
        self.url_bar.returnPressed.connect(self.load_url)
        self.load_button.clicked.connect(self.load_url)

        # Add the URL bar and load button to a QHBoxLayout
        self.layout = QHBoxLayout()
        self.layout.addWidget(self.url_bar)
        self.layout.addWidget(self.load_button)

        # Create a QWidget and set the layout as its layout
        self.container = QWidget(self)
        self.container.setLayout(self.layout)

        # Add the container widget to the main window's layout
        self.setLayout(self.container)

    def load_url(self):
        # Get the URL from the URL bar and load it in the QWebEngineView
        url = self.url_bar.text()
        self.view.load(QUrl(url))

app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())

This code creates a main window with a QWebEngineView widget for displaying web pages, a QLineEdit widget for entering URLs, and a QPushButton for loading the URL. The URL is loaded in the QWebEngineView when the user presses the load button or hits Enter in the URL bar. To build an executable file, you can use a tool such as PyInstaller. You can install PyInstaller using pip:

pip install pyinstaller

Then, you can create an executable file from your Python script by running the following command:

pyinstaller -w -F myscript.py

This will create a standalone executable file in the "dist" directory. You can specify the name of the executable file using the "-n" option, for example:

pyinstaller -w -F -n mybrowser myscript.py

I trust this helps you! if you have any query you can ask me.
