以下是 Python 中list和set的类图: "can be converted to"List+elements list+add(element) : void+remove(element) : voidSet+elements set+add(element) : void+remove(element) : void 结论 将列表转换为集合是一种常见的操作,可以帮助我们去除重复元素并利用集合的特性(如唯一性和高效性)。在实际应用中,...
The object in the update() method does not have to be a set, it can be any iterable object (tuples, lists, dictionaries etc.).Example Add elements of a list to at set: thisset = {"apple", "banana", "cherry"} mylist = ["kiwi", "orange"] thisset.update(mylist) print(this...

访问set集合元素 由于集合中的元素是无序的,因此无法向列表那样使用下标访问元素。访问集合元素最常用的方法是使用循环结构,将集合中的数据逐一读取出来。 DeletesetLikeother sequencetype.Wecan usedel()todeleteset as well.del(set1)OperationsofSet1.AddElementToadd elementstotheset collection,we can use thead...
