What are the advanced enumeration features in Python?

Python offers several advanced enumeration features, such as the enumerate() function, which allows you to loop over an iterable and get both the index and the value. Additionally, you can use collections.Counter for counting hashable objects, and itertools for creating enumerations with custom behavior.

Can you give me an example of using enumerate()?

Sure! Here's a simple example:

fruits = ['apple', 'banana', 'cherry']
for index, fruit in enumerate(fruits):
    print(index, fruit)

This will output:

0 apple
1 banana
2 cherry

What about using Counter from the collections module?

Counter is great for counting occurrences of elements. For example:

from collections import Counter

fruits = ['apple', 'banana', 'apple', 'orange', 'banana', 'banana']
count = Counter(fruits)
print(count)

This will output:

Counter({'banana': 3, 'apple': 2, 'orange': 1})
