How do I use the Counter class in Python?

The Counter class from the collections module helps count hashable objects. You can create a Counter by passing an iterable.

Can you show me an example of how to create a Counter?

Sure! Here's a simple example: from collections import Counter followed by my_counter = Counter(['a', 'b', 'a', 'c']). This will count the occurrences of 'a', 'b', and 'c'.

How can I access the count of a specific element?

You can access the count of a specific element by using the element as a key, like this: my_counter['a'] will return 2.

What if I want to get the most common elements?

You can use the most_common() method. For example, my_counter.most_common(2) will return the two most common elements and their counts.
