Python collections module – python counter, defaultdict, ordereddict, namedtuple free python course with 25 real time projects start now!! over the last few days, we opened ourselves up to three subclasses of the class ‘dict’, and function namedtuple(). We could use defaultdict to reduce the number of lines in the code. 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. 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. from collections import counter word count dict = counter () for w in text.split (" "): word count dict [w] =1. if we use counter, we can also get the most common words using a.
