Both counter and defaultdict (int) can work fine here, but there are few differences between them: counter supports most of the operations you can do on a multiset. so, if you want to use those operation then go for counter. counter won't add new keys to the dict when you query for missing keys. so, if your queries include keys that may not be. In python, dictionaries and tuples play a major role in creating efficient programs. in this article, we will learn about the counter, defaultdict, orderdict, and namedtuple classes present in the python collections module. python collections module. collections is a python built in module. we can simply import the module to use its objects. From collections import defaultdict word count dict = defaultdict(int) for w in text.split(" "): word count dict[w] =1 we could also have used counter to do this, which according to me is the most preferable method for this problem. Over the last few days, we opened ourselves up to three subclasses of the class ‘dict’, and function namedtuple(). in this python collections module tutorial, we will study python counter, python defaultdict, python ordereddict, and python namedtuple with their subtypes, syntax and examples. Class collections. counter ([iterable or mapping]) ¶. a counter is a dict subclass for counting hashable objects. it is a collection where elements are stored as dictionary keys and their counts are stored as dictionary values. counts are allowed to be any integer value including zero or negative counts.

Dictionary in python is an unordered collection of data values that are used to store data values like a map. unlike other data types that hold only single value as an element, the dictionary holds key value pair. in dictionary, the key must be unique and immutable. this means that a python tuple can be a key whereas a python list can not.
