How to find list intersection?

arrays, intersection, python

Solution

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]

Problem

``` 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?
