How to use the Python Webbrowser Module (Builtin)

A guide to Python’s Builtin webbrowser module


In Python, webbrowser is a module you can use to open websites. Webbrowser has 3 main functions. Open, open_new, and open_new_tab. They are basically the same. Supposedly, open_new will open a tab in a new window. I have tested that, and it does not work with Chrome, at least for my OS, ChromeOS. But, first let’s get into the code.


Webbrowser is builtin, so you do not have to install anything.

Importing Module

Since Webbrowser is builtin, you can just start by typing import webbrowser. Now we have webbrowser in. If you are in repl.it, you may have to install the dependencies, using the tab for that. I’m not sure, but I think, since it’s built in, you can just import webbrowser. I don’t know if repl.it supports it. It should, because you can easily open a new tab with html, css, JS, what repl.it is written in.

Opening a link

The first thing you will have to do, is type webbrowser.open([linktext]). You can also do webbrowser.open_new([linktext]). Finally, you can do webbrowser.open_new_tab([linktext]). If you want, you can have the code take input for the link. Then the link imputed will be opened in a tab. Because, it might be confusing, here is an example of a link: https://a-sub-domain.a-domain.an-end-thing/a-page.html.

The full code

Finally, here is the* full code, (I’m assuming you want to get input for the link):

import webbrowser

webpage = input(‘Please enter the webbpage here: ’)

webbrowser.open(‘https://’, webpage)

@RhinoRunner, please state your error, your code, and why when I go to moomoo.io, it looks like a gaming website

@RhinoRunner, it looks like this is a webbrowser problem. Try openning it in your local Command Line, For example, the Penguin Terminal for Linux, and the Command Prompt, for WindosOS

@RhinoRunner, this doesn't work on the web, because webbrowser is designed to use something like OS, that doesn't work on your website you use for code.

Addition: This was created on a Google Document, becuase I hate that repl.it doesn't save your work. So, if you would like to view this on a G-Doc, then just go to this link: https://docs.google.com/document/d/1L1pyqRbs8LdHRWu6J8bUYqFElgWPRyOZbYXCPlgjpoA/edit

Update: This will not work in repl.it, as you will see if you run the repl above. It has some issue, where it opens a window in repl, and it things it's something like a pygame app. So, repl.it users, I'm sorry, this won't work.
