Syntax error Python program to print all the common elements of two lists.

Python program to print all the common elements of two lists.

Given two lists, print all the common element of two lists.

Examples −

Input : L1 = [5, 6, 7, 8, 9] 
        L2 = [5, 13, 34, 22, 90]
Output : {5}

Explanation

The common elements of both the list is 5.

Algorithm

Step1 : create two user input lists.
Step2 : Convert the lists to sets and then print set1&set2.
Step3 : set1 and set2 returns the common elements set, where set1 is the list1 and set2 is the list2.

Example Code

# Python program to find the common elements  
# in two lists 
def commonelemnets(a, b): 
   seta = set(a) 
   setb = set(b) 
   if (seta & setb): 
      print("Common Element ::>",seta & setb) 
   else: 
      print("No common elements")  
              
A=list()
n=int(input("Enter the size of the First List ::"))
print("Enter the Element of First List ::")
for i in range(int(n)):
   k=int(input(""))
   A.append(k) 
B=list()
n=int(input("Enter the size of the Second List ::"))
print("Enter the Element of Second List ::")
for i in range(int(n)):
   k=int(input(""))
   B.append(k) 
commonelemnets(A,B)
