Answers for "python if two lists have intersection"

python intersection of two lists

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))

python check if two lists intersect

a = [1, 2, 3]
b = [3, 4, 5]

bool(set(a) & set(b))

python get the intersection of two lists

# intersection of two lists (lst1 & lst2)
In [1]: x = ["a", "b", "c", "d", "e"]

In [2]: y = ["f", "g", "h", "c", "d"]

In [3]: set(x).intersection(y)
Out[3]: {'c', 'd'}
# has_intersection = bool(set(x).intersection(y)) -> True
