a = [1,2,3,4,5] b = [1,3,5,6] c = a and b print c
How can we achieve a boolean AND operation (list intersection) on two lists?
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]
Using list comprehensions is a pretty obvious one for me. Not sure about performance, but at least things stay lists.
[x for x in a if x in b]
Or "all the x values that are in A, if the X value is in B".
