Python集合中difference方法返回两个集合的差集,差集中的元素存在于第一个集合而不在第二个集合中。difference方法语法:set.difference(*set)参数:*set 是可变参数,可以传入多个集合,一般都是传入一个集合。返回值:集合的差集。例如:set3 = set1.difference(set2)表示将 set1 中有而 set2 没有的元素给 se...
Pythonis a high-level and object-oriented programming language. It's an open-source language.Guido van Rossumcreated it in the year 1989. Over the years, many developers all over the world have contributed to Python. Consequently, there are outstanding modules and frameworks in Python which make...
set1 = {1, 2, 3, 4, 5} set2 = {4, 5, 6, 7, 8} result = set1.difference(set2) print(result) # 输出: {1, 2, 3} result = set2.difference(set1) print(result) # 输出: {8, 6, 7} 复制代码 在上面的示例中,set1和set2分别为两个集合。通过调用set1.difference(set2),我们...
集合是python中的数据容器之一,python中有很多的数据容器,有列表,元组,字符串等,但它们都只是针对本身操作,取出,删除,替换,都是针对自己,而集合不同,两个集合之间可以取不同之处,生成一个新的元素 set1 = {1, 2, 3, 4} set2 = {1, 7, 8, 9} set3 = set1.difference(set2)当我们运行此...
🐛 Describe the bug I am trying to implement code on CPP, However, I found that the permute and transpose functions in cpp have different values from permute python3. Besides, the tensor after view is the same and I also try output = tens...

Is there a difference between == and is in Python - In Python and many other programming languages, a single equal mark is used to assign a value to a variable, whereas two consecutive equal marks is used to check whether 2 expressions give the same valu
Python字典的difference_update方法从一个集合中删除另一个集合的所有元素,本质上就是删除两个集合的交集部分。 与difference方法对比,difference方法返回集合的差集,而difference_update则是从原集合里删除两个集合的交集部分。 difference_update语法:s1.difference_update(s2) ...

1,交集&,即:两个集合中都共有的元素 2,并集|,即:两个集合中的所有元素,相同的元素要被删除 3,差集-,即:集合一有但是集合二没有的元素 (注意📢:上面的三个操作都不是对原集合进行修改,而是返回一个新的集合) 下面是集合定义的示例👇🏻 代码语言:javascript 代码运行次数:0 运行 AI代码解释 s1 = {...
