How to find list intersection?
a = [1,2,3,4,5]
b = [1,3,5,6]
c = a and b
print c
actual output: [1,3,5,6]
expected output: [1,3,5]
How can we achieve a boolean AND operation (list intersection) on two lists?
Answer
If order is not important and you don't need to worry about duplicates then you can use set intersection:
>>> a = [1,2,3,4,5]
>>> b = [1,3,5,6]
>>> list(set(a) & set(b))
[1, 3, 5]
