How can I create an advanced counter in Python?

You can create an advanced counter using the collections.Counter class. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

from collections import Counter

# Sample data
words = ['apple', 'banana', 'apple', 'orange', 'banana', 'banana']

# Create a counter
word_count = Counter(words)

print(word_count)

This will count the occurrences of each word.

How can I customize the counter to count only specific items?

You can filter the items you want to count by using a list comprehension. For example:

filtered_count = Counter(word for word in words if word in ['apple', 'banana'])
