For example: X = {1, 3, 5, 7} Y = {2, 3, 5, 8} print(X.intersection(Y)) Output: {3, 5} The intersection() function in Python has a temporal complexity of O(min(len(set1), len(set2))), where set1 & set2 are the sets that are being intersected. This indicates ...
>>>set(a).union(b)set([1,2,3,5]) 交集 >>>a=[1,3,5]>>>b=[1,2,3]>>>set(a)&set(b)set([1,3]) 或者 >>>set(a).intersection(b)set([1,3])>>> 差集 >>>a=[1,3,5]>>>b=[1,2,3]>>>set(a)-set(b)set([5]) 或者 >>>set(a).difference(b)set([5])>>> ...
intersection() 方法用于返回两个或更多集合中都包含的元素,即交集。语法intersection() 方法语法:set.intersection(set1, set2 ... etc)参数set1 -- 必需,要查找相同元素的集合 set2 -- 可选,其他要查找相同元素的集合,可以多个,多个使用逗号 , 隔开...
The intersection_update() method doesn't return any value. Example: Python Set intersection_update() A = {1, 2, 3, 4} B = {2, 3, 4, 5, 6} C = {4, 5, 6, 9, 10} # performs intersection between A, B and C and updates the result to set A A.intersection_update(B, C...
