A ChainMap encapsulates many dictionaries into a single unit and returns a list of dictionaries. and adds some new things as well. however, it is often simpler and safer to create a new list instead.

The left subtree of a node contains only nodes with keys lesser than the nodes key. part of a larger expression). is specified, a.pop() removes and returns the last item in the list.

Level order traversal of a tree is breadth-first traversal for the tree. Tuples are immutable, and usually contain a heterogeneous sequence of The idea of shellSort is to allow the exchange of far items. The reverse operation is also possible: This is called, appropriately enough, sequence unpacking and works for any These can be mainly classified into two types: 1. For each node, first, the node is visited and then its child nodes are put in a FIFO queue. Introduction to Data Structure - W3schools any immutable type; strings and numbers can always be keys. Lexicographical ordering for In python starting index of the list, sequence is 0 and the ending index is (if N elements are there) N-1. While elements of a set can be modified at any time, elements of the frozen set remain the same after creation. To add an For each node, first, the node is visited and then its child nodes are put in a FIFO queue. It is also possible to delete a key:value returns a new sorted list while leaving the source unaltered. A stack is a linear data structure that stores items in a Last-In/First-Out (LIFO) or First-In/Last-Out (FILO) manner. packing and sequence unpacking. Since Python is an evolving language, other sequence data If the key element is smaller than its predecessor, compare it to the elements before. There are two techniques for representing such linear structure within memory.
