Importing the Webbrowser Module

The webbrowser module is part of the standard Python library, so no additional installation is required. To use the module in your Python script, import it using the following code:

import webbrowser

Once you’ve imported the webbrowser module, you’ll have access to all its functions and features and be able to perform various web browsing tasks in your Python script. In the next section, you’ll learn how to use the webbrowser module to open a web page.

Opening a Web Page using the Webbrowser Module

To open a web page using the webbrowser module, you can use the open() function. This function takes a single argument, which is the URL of the web page that you want to open. For example, the following code opens the Python homepage in your default web browser:

import webbrowser
webbrowser.open("https://www.python.org")

The open() function launches the default web browser on your system and loads the specified URL. If the browser is already open, the open() function simply opens a new tab with the specified URL. You can also use the open() function to open a local HTML file by specifying the file path in place of the URL.

In the next section, you’ll learn how to navigate the history of a web page using the webbrowser module.

Navigating the History of a Web Page using the Webbrowser Module

The webbrowser module provides a few functions for navigating the history of a web page. For example, you can use the back() function to go back to the previous page in the history, or the forward() function to go forward to the next page in the history. To use these functions, you first need to create a webbrowser controller object using the get() function, like this:

import webbrowser
browser = webbrowser.get()

With the browser controller object, you can now navigate the history of a web page. For example, the following code goes back to the previous page in the history:

browser.back()

And the following code goes forward to the next page in the history:

browser.forward()

Note that these functions only affect the current browser window. If you have multiple tabs open, you may need to switch to the desired tab before using these functions.

Customizing the Default Web Browser using the Webbrowser Module

By default, the webbrowser module uses the default web browser set on your system. However, you can also specify a different browser to use by setting the webbrowser.register() function. For example, to use Google Chrome as your default browser, you can use the following code:

import webbrowser
webbrowser.register('chrome', None, webbrowser.BackgroundBrowser("google-chrome"))

The first argument is the browser name, the second is the preferred instance, and the third is the browser controller. The available browser controllers can be found in the webbrowser module documentation.

Once you’ve registered a custom browser, you can use it as the default browser by specifying its name as an optional argument to the open() function, like this:

webbrowser.open("https://www.python.org", new=0, autoraise=True, browser="chrome")

In this example, the new argument specifies that a new browser window should be opened if there isn’t already one open, and the autoraise argument specifies that the browser window should be raised to the top.

Controlling the Size and Position of the Web Browser Window using the Webbrowser Module

The webbrowser module does not provide direct support for controlling the size and position of the web browser window. However, you can use a third-party library such as PyAutoGUI to automate GUI tasks, including controlling the size and position of the web browser window.

With PyAutoGUI, you can control the size and position of the web browser window using the size() and moveTo() functions, respectively. For example, the following code resizes the web browser window to 800×600 pixels and moves it to the position (100, 100) on the screen:

import pyautogui

# Resize the window to 800x600
pyautogui.size(800, 600)

# Move the window to position (100, 100)
pyautogui.moveTo(100, 100)

PyAutoGUI requires the GUI window to be active in order to control it, so you may need to switch to the desired window before using these functions.

In this tutorial, you’ve learned how to use the Python webbrowser module to perform various web browsing tasks, including opening a web page, navigating the history, customizing the default web browser, and controlling the size and position of the web browser window. With these skills, you can now automate web browsing tasks in your Python scripts, making your work more efficient and streamlined.
