WebA is subset of B: True B is subset of A: False. In the above example, we have used the issubset () method to check if sets A and B are subsets of each other. Since all elements of A are present in B, the issubset (B) method returns True. On the other hand, set B is not a subset of A. Thus, we get the False with issubset (A). WebAug 8, 2024 · You can use theissubset()method to check for subset in python as follows.
