Python program to find Union of two or more Lists?
Union operation means, we have to take all the elements from List1 and List 2 and all the elements store 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.
Example 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 ::>",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 ::> [23, 11, 22, 33, 33, 22, 67, 45]
