Can you explain itertools.groupby?

Can you explain how itertools.groupby works in Python?

Sure! The itertools.groupby function groups adjacent elements in an iterable that have the same value.

Can you give me an example of how to use it?

Of course! Here's a simple example: If you have a list like [1, 1, 2, 2, 3], using groupby will group the 1s together, the 2s together, and the 3s.

What do I need to import to use it?

You need to import it from the itertools module: from itertools import groupby.

Are there any limitations to using groupby?

Yes, groupby only groups adjacent elements, so you may need to sort your data first if you want to group all identical elements.
