How can I make Python's 'webbrowser' block execution?

Question

I want to implement a Python script to act as my OAuth2 endpoint, since I'm trying to write a Soundcloud app. Part of the authentication process involves visiting a Soundcloud page where you can sign in and grant access to the given Soundcloud application.

I'd like to be able to open that webpage in a browser using Python 3, which you can do with the webbrowser object. You can see on the documentation that launching a text-based browser blocks execution; I want to block execution whilst the webpage is open in a GUI-based browser.

Does anyone know whether this is possible?

Answer 1

This might be impossible to do portably. For example, if Firefox is already running on Linux, the second invocation of firefox http://url will find out that an instance using the same profile, will send a message to the other process to open that URL in a tab, then exits immediately.

However, you could accomplish the same thing by sending the authentication tokens to a server, and simultaneously polling the server for credentials in the python script.
