首先,我们需要选择要union的两种数据类型。一般来说,可以是Python中的列表(list)、集合(set)、元组(tuple)等数据类型。这里以列表和集合为例进行说明。 list1=[1,2,3,4,5]set1={4,5,6,7,8} 1. 2. 步骤2:创建一个新的数据结构来存储union后的结果 接下来,我们需要创建一个新的数据结构来存储union后...
Python Setx.union(y)method finds the union of setxand setyand returns the resulting set. We can pass more than one set to the union() method as arguments. In this tutorial, we will learn the syntax of set.union() method and go through examples covering different scenarios for the argumen...
python的set和其他语言类似, 是一个无序不重复元素集, 基本功能包括关系测试和消除重复元素。 集合对象还支持union(联合), intersection(交), difference(差)和sysmmetric difference(对称差集)等数学运算。 sets 支持 x in set的bool运算判别x是否在集合内, len(set)集合的长度,和 for x in set对集合内数据的...
>>> 差集 >>>a=[1,3,5]>>>b=[1,2,3]>>>set(a) -set(b)set([5])# 或者>>>set(a).difference(b)set([5]) >>> 对称差集 返回两个集合中不重复(不同)的元素>>>a=[1,3,5]>>>b=[1,2,3]>>>set(a) ^set(b)set([2,5])# 或者>>>set(a).symmetric_difference(b)set([2...

Python Set intersection() Python Set symmetric_difference()Before we wrap up, let’s put your knowledge of Python set union() to the test! Can you solve the following challenge? Challenge: Write a function to get the sum of union of two sets. Return the sum of all elements in the un...
If an item is present in more than one set, the result will contain only one appearance of this item. As a shortcut, you can use the|operator instead, see example below. Syntax set.union(set1, set2...) Parameter Values ParameterDescription ...
In parameters, any number of sets can be given 返回值: The union() function returns a set, which has the union of all sets(set1, set2, set3…) with set1. It returns a copy of set1 only if no parameter is passed. 以下是上述方法的Python3实现: ...
my_set={1,2,3,4,5}my_set.clear()print(my_set)#输出:set()代表空集合 3,两个集合的合并 union将两个结合合并 (注意📢:原集合不会被修改,返回一个合并好以后的新集合) 🔍语法: 代码语言:javascript 复制 集合1.union(集合2) 示例👇🏻 ...
Amongst the features introduced in the Python Typing library, was Union, which can be used to specify multiple possible types for a variable.
