Check if multi dimensional list element exists in another list

Consider these two lists:

ListA = ["High", [1,2,3], "Medium"]
ListB = [["Low", [3,2,1], "Low"], ["High", [1,2,3], "Medium"]]

Now I want to check if ListA exists in ListB.
In this example, it should give TRUE since ListA equals ListB[1].

Normally I would convert the list to a set so all duplicates get removed, however, since this is not a flat list I’m stuck finding a good way to solve this.

>Solution :

if ListA in ListB:
    print('ListA exists in ListB.')
