>>> y = int(input('Please enter a number'))
Please enter a number45
>>> x+y
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: must be str, not int
>>> y+y

Simple Queue Implementation using Python

Stacks and Queues are not data structures, they are basically abstract data types. The simple data structure can be an array or a linked list. Queues are FIFO.. First In and First Out. Queues do have real world operations like:- 1.    Token System 2.    Organising data to archive based on age. 3.    Scheduling 4.    Any task which involves first come first serve basis. Below is a simple implementation of Queue using Python. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 class Queue : def __init__ ( self ): self . queue = [] def isEmpty ( self ): return self . queue == [] def enqueue ( self , data): self . queue . append(data) def dequeue ( self ): data = self . queue[ 0 ] del self . queue[ 0 ] return data def peek ( self ): return se...

Appian function merge()

Lets have a look at merge() function . It takes a number of list and combines them to create a new list. Takes an element sequentially from each list and append it to the major list. Below are some of the examples. merge({ 10 , 50 }, { 60 , 40 }) Value 10 ; 60 ; 50 ; 40 merge({ 10 , 30 }, { 20 , 40 , 50 }) Value 10 ; 20 ; 30 ; 40 ; ; 50 merge({ 10 , 30 }, { 20 , 40 , 50 }, { 60 }) Value 10 ; 20 ; 60 ; 30 ; 40 ; ; ; 50 ; #After the last semicolon one elelent exist merge({ 10 , 30 }, { 20 , 40 , 50 }, { 60 , 70 , 80 }) Value 10 ; 20 ; 60 ; 30 ; 40 ; 70 ; ; 50 ; 80 merge({ 1 , 2 , 3 }, { 4 , 5 , 6 }) returns 1 , 4 , 2 , 5 , 3 , 6 Source
