Using the itertools.groupby function to group a list of elements based on a common key. #python

Hey Python developers!

Let's say we have a list of tuples, where each tuple contains a name and a score, and we want to group the tuples by score.

The groupby function takes two arguments: an iterable to group, and a function that returns a key for each element in the iterable.

In this example, the lambda function lambda x: x[1] is used as the key function, which returns the score for each tuple in the list.

And that's it!

With just a few lines of code, we can group a list of elements based on a common key.

Thanks for watching, and happy coding!
