Concatenating two or more lists in Python

Python Methods and Functions

The concatenation operation means that we have to take all the elements from List1 and List 2, and store all the elements in another third list.



 List1 :: [1,2,3] List2 :: [4,5,6] List3 :: [1,2 , 3,4,5,6] 



Algorithm

 Step 1: Input two lists. Step 2: for union operation we just use + operator. 



Sample code

 # UNION OPERATION A = list () B = list () n = int (input (" Enter the size of the List :: ")) print (" Enter the Element of first list :: ") for i in range (int (n)): k = int (input (" ")) A.append (k ) print ("Enter the Element of second list ::") for i in range (int (n)): k = int (input ("")) B.append (k) C = A + B print ("THE FINAL LIST IS :: & gt; ", C) 



Output

 Enter the size of the List :: 4 Enter the Element of first list :: 23 11 22 33 Enter the Element of second list :: 33 22 67 45 THE FINAL LIST IS :: & gt; [23, 11, 22, 33, 33, 22, 67, 45]
