We can combine two or more sets together and get a combined set as a result. To do this we usepython set unionmethod. We can also use“|” operatorto get the same result inPython Programming. To learn this lesson of python, we will give different examples below. You can also check t...
Union of three set shown in green color Example 2: Set Union Using the | Operator You can also find the union of sets using the | operator. A = {'a', 'c', 'd'} B = {'c', 'd', 2 } C = {1, 2, 3} print('A U B =', A| B) print('B U C =', B | C) ...
相反,它们的运算符版本(operator based counterparts)要求参数必须是 sets。这样可以避免潜在的错误,如:为了更可读而使用 set('abc') & 'cbs' 来替代 set('abc').intersection('cbs')。从 2.3.1 版本中做的更改:以前所有参数都必须是 sets。 另外,Set 和 ImmutableSet 两者都支持 set 与 set 之间的比较。...
在2 月份发布的 Python 3.9.04a 版本中,新增了一个抓眼球的新操作符操作符:|, PEP584 将它称之为合并操作符(Union Operator),用它可以很直观地合并多个字典。 >>> profile = {"name": "xiaoming", "age": 27} >>> ext_info = {"gender": "male"} ...
请注意:union(), intersection(), difference() 和 symmetric_difference() 的非运算符(non-operator,就是形如 s.union()这样的)版本将会接受任何 iterable 作为参数。相反,它们的运算符版本(operator based counterparts)要求参数必须是 sets。这样可以避免潜在的错误,如:为了更可读而使用 set('abc') & 'cbs' ...

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, len(set),和 for x in ...
set2Optional. The other iterable to unify with. You can compare as many iterables as you like. Separate each iterable with|(a pipe operator). See examples below. More Examples Example Use|as a shortcut instead ofunion(): x ={"apple","banana","cherry"} ...
