union()方法可以让Set或者类Set对象的值进行合并(同时去重)处理。 语法示意: set1.union(set2) 数学公式表示: A∪B={x∣x∊Aorx∊B} 图形表示: 案例示意 constarr1 = ['CSS世界','CSS新世界','HTML并不简单'];constarr2 = ['CSS选择器世界','CSS新世界'];// 合并去重console.log([...newSe...

set1.intersect(set2) difference set1 - set2 set1.difference(set2) 交集& :x&y,返回一个新的集合,包括同时在集合 x 和y中的共同元素。 并集| :x|y,返回一个新的集合,包括集合 x 和 y 中所有元素。 差集- :x-y,返回一个新的集合,包括在集合 x 中但不在集合 y 中的元素。
The difference of sets is one of the important and fundamental set theory operations. Union and intersection are the other set theory operations in addition to the difference of sets. The difference of two sets A and B is again a set that consists of the elements of A that are NOT in B...
python的集合set和其他语言类似,是一个无序不重复元素集, 可用于消除重复元素。 支持union(联合), intersection(交), difference(差)和sysmmetric difference(对称差集)等数学运算。不支持 indexing, slicing, 或其它类序列(sequence-like)的操作。因为,sets作为一个无序的集合,sets不记录元素位置或者插入点。下面就...
