Python compare two lists return True or False

Compare two lists and return Boolean

I would use MapSet.subset?/2 here:

iex(1)> list1 = [1, 2, 3, 4, 5, 6, 7] [1, 2, 3, 4, 5, 6, 7] iex(2)> list2 = [3, 4, 5] [3, 4, 5] iex(3)> MapSet.new(list2) |> MapSet.subset?(MapSet.new(list1)) true iex(4)> list2 = [3, 4, 5, 9] [3, 4, 5, 9] iex(5)> MapSet.new(list2) |> MapSet.subset?(MapSet.new(list1)) false

This will run in O(n log n) time as opposed to Kernel.--/2 which runs in O(n^2). (This won't make a significant difference for small lists though.)


Check if length(list2 -- list1) is equal to zero


You can use MapSet.equal?:

iex(1)> MapSet.equal?(MapSet.new(list1), MapSet.new(list2)) true iex(2)> list1 = [1,2,3,4,5,6,7] [1, 2, 3, 4, 5, 6, 7] iex(3)> list2 = [3,4,5] [3, 4, 5] iex(4)> MapSet.equal?(MapSet.new(list1), MapSet.new(list2)) false

    Python Difference Between Two Lists. Lists in Python can be performed in different ways, but it depends on the outcome required. Two popular methods of comparison are set() and cmp(). The set() function creates an object that is a set object. The cmp() function is used to compare two elements or lists and return a value based on the arguments passed.

    If you want a set of items in either list but not both lists use the symmetric difference operator '^'. [1,2,3,4,5] ^ [3,4,5,6,7] = [1,2,6,7] The symmetric difference operator, assuming it does what you want, also has the advantage of being commutative.
