In Python, webbrowser module is a convenient web browser controller. It provides a high-level interface that allows displaying Web-based documents to users. 

webbrowser can also be used as a CLI tool. It accepts a URL as the argument with the following optional parameters: -n opens the URL in a new browser window, if possible, and -t opens the URL in a new browser tab. 

Python




python -m webbrowser -t "https://www.google.com"

NOTE: webbrowser is part of the python standard library. Therefore, there is no need to install a separate package to use it.

The webbrowser module can be used to launch a browser in a platform-independent manner as shown below:
Code #1 : 

Python3




import webbrowser
webbrowser.open('http://www.python.org')

Output : 

True

This opens the requested page using the default browser. To have a bit more control over how the page gets opened, use one of the following functions given below in the code –
Code #2 : Open the page in a new browser window. 

Python3




webbrowser.open_new('http://www.python.org')

Output : 

True

Code #3 : Open the page in a new browser tab. 

Python3




webbrowser.open_new_tab('http://www.python.org')

Output : 

True

These will try to open the page in a new browser window or tab, if possible and supported by the browser. To open a page in a specific browser, use the webbrowser.get() function to specify a particular browser.
Code #4 : 

Python3




c = webbrowser.get('firefox')
 
c.open_new_tab('http://docs.python.org')

Output : 

True
True

Being able to easily launch a browser can be a useful operation in many scripts. For example, maybe a script performs some kind of deployment to a server and one would like to have it quickly launch a browser so one can verify that it’s working. Or maybe a program writes data out in the form of HTML pages and just like to fire up a browser to see the result. Either way, the webbrowser module is a simple solution.
