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. Python collections module. the collection module in python provides different types of containers. a container is an object that is used to store different objects and provide a way to access the contained objects and iterate over them. some of the built in containers are tuple, list, dictionary, etc. Collections in python are basically container data types, namely lists, sets, tuples, dictionary. they have different characteristics based on the declaration and the usage. a list is declared in square brackets, it is mutable, stores duplicate values and elements can be accessed using indexes. Python’s regular dictionaries were unordered data structures for years. so, back in 2008, pep 372 introduced the idea of adding a new dictionary class to collections. the new class would remember the order of items based on the moment in which keys were inserted. that was the origin of ordereddict. ordereddict was introduced in python 3.1. Python 3 has a number of built in data structures, including tuples, dictionaries, and lists. data structures provide us with a way to organize and store data. the collections module helps us populate and manipulate data structures efficiently. in this tutorial, we’ll go through three classes in the collections module to help you work with.

Collections¶. we have already encountered some simple python types like numbers, strings and booleans. now we will see how we can group multiple values together in a collection – like a list of numbers, or a dictionary which we can use to store and retrieve key value pairs. I would like to leverage some templated collection (from the python collections module) to easily sort and compare as list or set of virtualpage classes. also would like some advice on the layout of my data storage classes: virtualpage and physicalpage. given either a sequence of virtualpages or as in the example below:. This module provides abstract base classes that can be used to test whether a class provides a particular interface; for example, whether it is hashable or whether it is a mapping. an issubclass() or isinstance() test for an interface works in one of three ways.
