How can I use the collections module with lists in Python?

You can use the collections module to enhance list functionalities. For example, you can use Counter to count elements.

Can you show me an example of using Counter with a list?

Sure! Here's a simple example:

from collections import Counter

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

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

What other features does the collections module offer?

The collections module offers several features like defaultdict, namedtuple, deque, and OrderedDict, each serving different purposes.

How do I use defaultdict with lists?

You can use defaultdict to create a dictionary that defaults to a list. For example:

from collections import defaultdict

my_dict = defaultdict(list)
my_dict['fruits'].append('apple')
print(my_dict)

This will output: defaultdict(<class 'list'>, {'fruits': ['apple']}).
