We will provide you an example of how you can get the results of the Euroleague games in a structured form. The example is from the 2016-2017 season but you can adapt it for any season. What you need is to get the corresponding URL for each team in Euroleague and also to define the period.

Let’s start coding:

Let’s see the df how does it look like:

This is a good starting point in case you want to build a predictive model.
