union()方法用于查找所有集合的并集，此方法以该集合( set1 )调用，其他集合( set1，set2，... )可以作为参数提供，方法返回包含所有元素的集合所有集合中的所有元素(常见元素仅重复一次)。

Syntax:

句法：

set1.union(set2, set3, ...)

Parameter(s):

参数：

• set2, set3, ... – Here, set2 is required and other sets are optional.

Example 1:

范例1：

# Python Set union() Method with Example# declaring the setscars_1 = {
   "Porsche", "Audi", "Lexus"}cars_2 = {
   "Porsche", "Mazda", "Lincoln"}# finding the union of both setsx = cars_1.union(cars_2)# print the setprint("cars_1: ", cars_1)print("cars_2: ", cars_2)print("x: ", x)

Output

输出量

cars_1:  {'Porsche', 'Audi', 'Lexus'}cars_2:  {'Porsche', 'Mazda', 'Lincoln'}x:  {'Porsche', 'Mazda', 'Lincoln', 'Audi', 'Lexus'}

Example 2:

范例2：

# Python Set union() Method with Example# declaring the setsx = {
   "ABC", "PQR", "XYZ"}y = {
   "ABC", "PQR", "XYZ"}z = {
   "DEF", "MNO", "ABC"}# finding the union of all setsresult = x.union(y,z)# printing the setsprint("x: ", x)print("y: ", y)print("result: ", result)

Output

输出量

x:  {'ABC', 'PQR', 'XYZ'}y:  {'ABC', 'PQR', 'XYZ'}result:  {'PQR', 'MNO', 'DEF', 'ABC', 'XYZ'}
