Can you explain the difference between a Counter and a Dictionary in Python?
Sure! A Dictionary is a built-in data type that stores key-value pairs, while a Counter is a subclass of Dictionary specifically designed to count hashable objects.
How does a Counter work? Can you give me an example?
A Counter counts the occurrences of elements in an iterable. For example, from the list [1, 2, 2, 3], a Counter would return Counter({2: 2, 1: 1, 3: 1}).
Are there any methods that are unique to Counter?
Yes, Counters have unique methods like most_common()
which returns the n most common elements and their counts.
Can I use a Counter like a regular dictionary?
Absolutely! You can access, add, and modify elements in a Counter just like you would with a regular dictionary.
