s.discard(element),如果要删除的元素不存在,也不会报错 s.discard(element)删除一个元素 s.update(s2),用一个新的集合的元素来更新到当前集合s中 s.remove(element)要删除的元素不存在,则会报错:KeyError: result = s.pop()每次删除的都是第一个元素 s.add(element) 添加元素。添加后,会自动去重。 39....
Also, you can access any element of the list by its index which is zero based.third_elem = mylist[2]There are some similarities with strings. You can review the Python programming basics post.Mutable Lists/改变列表Lists are mutable because items can be changed or reordered....
Add Add(value) Adds an element to the end of a given tuple and a returns a new tuple. This method doesn't change a tuple in-place but instead creates a new tuple: letxs=(1,2,3)xs=xs.Add(4)xs//equals to (1,2,3,4)
元素访问(Element Access):可以通过索引访问Tuple的元素,例如 myTuple.Item1、 myTuple.Item2等。 可命名元素(Named Elements):在ValueTuple中,元组的元素可以具有命名,例如 ValueTuple<int, string> person = (Age: 25, Name: "Alice");。 LINQ支持(LINQ Support):Tuple可以用于LINQ查询,方便数据处理和筛选。
其格式如下:tuple-name=(element1,element2,...) 1#空元组2>>>tup1 =()3#单个元素需要增加一个‘,’4>>>tup2 =(1,)5>>>printtup1, tup26() (1,) 一个可变的tuple: 1>>> t = ('a','b', ['A','B'])2>>> t[2][0] ='X'3>>> t[2][1] ='Y'4>>>t5('a','b', [...
