Collections.namedtuple() python
collections.namedtuple() Basically, namedtuples are easy to create, lightweight object types. They turn tuples into convenient containers for simple tasks. With namedtuples, you don’t have to use integer indices for accessing members of a tuple. Example Code 01 >>> from collections import namedtuple >>> Point = namedtuple('Point','x,y') >>> pt1 = Point(1,2) >>> pt2 = Point(3,4) >>> dot_product = ( pt1.x * pt2.x ) +( pt1.y * pt2.y ) >>> print dot_product 11 Code 02 >>> from

collections.OrderedDict An OrderedDict is a dictionary that remembers the order of the keys that were inserted first. If a new entry overwrites an existing entry, the original insertion position is left unchanged. Example Code >>> from collections import OrderedDict >>> >>> ordinary_dictionary = {} >>> ordinary_dictionary['a'] = 1 >>> ordinary_dictionary['b'] = 2 >>> ordinary_dictionary['c'] = 3 >>> ordinary_dictionary['d'] = 4 >>> ordinary_dictionary['e'] = 5 >>> >>> print

You are given n words. Some words may repeat. For each word, output its number of occurrences. The output order should correspond with the input order of appearance of the word. See the sample input/output for clarification. Note: Each input line ends with a "\n" character. Constraints: 1<=n<=10^5 The sum of the lengths of all the words do not exceed 10^6 All the words are composed of lowercase English letters only. Input Format The first line contains the integer, n. The n

collections.deque() A deque is a double-ended queue. It can be used to add or remove elements from both ends. Deques support thread safe, memory efficient appends and pops from either side of the deque with approximately the same O(1) performance in either direction.
