def intersection(lst1, lst2): 
    lst3 = [value for value in lst1 if value in lst2] 
    return lst3 
  
# Driver Code 
lst1 = [4, 9, 1, 17, 11, 26, 28, 54, 69]

How to Get the Intersection of Sets in Python

firstSet = {2, 3, 4, 5}

secondSet = {1, 3, 5, 7}

print(firstSet & secondSet)
# {3, 5}

intersection of two lists using set method

# Python program to illustrate the intersection
# of two lists using set() method
def intersection(lst1, lst2):
    return list(set(lst1) & set(lst2))
 
# Driver Code
lst1 = [15, 9, 10, 56, 23, 78, 5, 4, 9]
lst2 = [9, 4, 5, 36, 47, 26, 10, 45, 87]
print(intersection(lst1, lst2))
