Python 集合操作：添加、删除、更新和输出

n = int(input()) MySet = set() for i in range(n): operation = input().split() if operation[0] == 'add': MySet.add(operation[1]) elif operation[0] == 'print': print(sorted(list(MySet))) elif operation[0] == 'del': if operation[1] in MySet: MySet.remove(operation[1]) elif operation[0] == 'update': MySet.update(set(operation[1].split(','))) elif operation[0] == 'clear': MySet.clear()
