intersection()method returns the intersection of setAwith all the sets (passed as argument). If the argument is not passed tointersection(), it returns a shallow copy of the set (A). Example 1: Python Set inter
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...

set1.intersection(set2, set3, set4….) 在参数中,可以给出任意数量的集合 Python交集()返回值: intersection() 函数返回一个集合,它具有所有集合(set1, set2, set3…) 与 set1 的交集。仅当未传递参数时,它才会返回 set1 的副本。 Python intersection()示例 示例1:set intersection()的工作 Python3实...
python intersection用法 【问题描述】:Difference between union() and update() in sets, and others? Python 集合有这些方法: s.union(t) s | t new set with elements from both s and t s.update(t) s |= t return set s with elements added from t...
""" 实验平台:Google colab """ import random import time import numpy as np def set_intersection(length=10000, interval=100000): a = set(random.sample([i for i in range(interval)], length)) b = set(random.sample([i for i in range(interval)], length)) time_1, time_2 = [], ...
In this code, we convertlist1andlist2to sets usingset()function, find the union usingunion()function, and then convert the resulting set back to a list usinglist()function. Conclusion In this article, we discussed theintersectionandunionfunctions in Python. These functions are useful when we ...
