Python provides a special type of function called namedtuple() that comes from the collection module. Named Tuples are similar to a dictionary but supports access from both the value and the key, where dictionary support access only by key. import collections Record = collections.namedtuple('Recor...

The best way to implement Python’s container data types, such as tuples, sets, lists, dicts, etc., is through the collection module. Employing the collection module for these container data types – UserString, Counter, OrderedDict, Chainmap, ChainMap, UserList, and namedtuple() can largely...
