Checking if all elements of a List of Lists are in another List of Lists Python

Question

My question is, how do you check if all of the elements of a list of lists are in another list of lists? Or maybe better phrased, how do you check if one list of lists

Answer 1

Convert your sublists to tuples, for example:

In [2]: a = [[2,3],[5,6],[8,9]]

In [3]: b = [[2,3],[5,6],[8,9], [10,11]]

In [4]: set(tuple(x) for x in a).issubset(tuple(x) for x in b)
Out[4]: True
