Creating Desktop Applications with Tkinter and Python - Part 4

This is the fourth video of the series of creating a graphical application with tkinter and Python. We're extending the functionality of the search bar by allowing a convenient switch between search engines (Google and DuckDuckGo).

We start by expanding the previously defined functions 'callback' and 'get'. The new functionality/feature is going to be complete in the next video, with the creation of two radio buttons.
