intersection of set and list python code example

Example 1: intersection in list

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] 
lst2 = [9, 9, 74, 21, 45, 11, 63, 28, 26] 
print(intersection(lst1, lst2))

Example 2: python set intersection

both = {'a', 'A', 'b', 'B'}
some = {'a', 'b', 'c'}
result1 = both & some
# result: {'a', 'b'}
result2 = both.intersection(some)

print(result1 == result2)
# True
