Counter Collections In Python A Counter Is A Subclass

I want to know how many items are in a python counter, including the duplicates. i tried len and it tells me the number of unique items: >>> c = counter(x=3,y=7) >>> len(c) 2 the best i have is sum(c.itervalues()) which i suppose isn't terrible, but i was hoping the counter object caches the value so i could access it in o(1). The counter is a sub class available inside the dictionary class. using the python counter tool, you can count the key value pairs in an object, also called a hash table object. why use python counter? here, are major reasons for using python 3 counter: the counter holds the data in an unordered collection, just like hashtable objects. Its count is 0. $ python collections counter get values.py a : 3 b : 2 c : 1 d : 1 e : 0 elements. the elements() method returns an iterator over elements repeating each as many times as its count. elements are returned in arbitrary order. import collections c = collections.counter('extremely') c['z'] = 0 print c print list(c.elements()). 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. Earlier, we discussed three classes from python module collections. today, we’ll talk about another such class python counter. here, we will study initializing, updating, accessing, and reassigning counters in python. moreover, we will learn python counter list, loops and arithmetic. so, let’s start the python counter tutorial.
