A simple naive approach is to use two for loops and check if the whole list A is contained within list B or not. If such a position is met in list A, then break the loop and return true, otherwise false.

Python – Check List Contains All Elements Of Another List
The most straightforward way to check if an item is in a list in Python is using the 'in' operator. The 'in' operator checks if a specified item is present in the list.
