python - How to check if all elements in a tuple or list are in another?

Question

For example, I want to check every elements in tuple (1, 2) are in tuple (1, 2, 3, 4, 5). I don't think use loop is a good way to do it, I think it could be done in one line.

Answer 1

You can use set.issubset or set.issuperset to check if every element in one tuple or list is in other.

>>> tuple1 = (1, 2)
>>> tuple2 = (1, 2, 3, 4, 5)
>>> set(tuple1).issubset(tuple2)
True
>>> set(tuple2).issuperset(tuple1)
True
