How can I use the Counter class from the collections module in Python?

The Counter class is a part of the collections module in Python and is used to count hashable objects. You can create a Counter by passing an iterable, like a list or a string, to it.

Can you show me a simple example of how to use it?

Sure! Here's a simple example:

from collections import Counter

# Example list
my_list = ['apple', 'banana', 'apple', 'orange', 'banana', 'banana']

# Create a Counter object
counter = Counter(my_list)

print(counter)

This will output: Counter({'banana': 3, 'apple': 2, 'orange': 1}).

What if I want to count characters in a string?

You can use the Counter in the same way. For example:

from collections import Counter

my_string = 'hello world'
counter = Counter(my_string)
print(counter)

This will count each character in the string.
