区别:remove()和discard()都是对set集合中的元素进行删除,不同的是,remove()方法删除不存在的元素时会报错,但是discard()方法不会报错 Symmetric_difference() 返回两个集合中不重复的元素集合(对称差集) 注意:会产生新的集合 symmetric_difference_update() 移除两个集合的相同元素,增加不同的元素(对称差集) 注...
The only difference is that the decorator will receive a class and not a function as an argument. In fact, all the decorators that you saw above will work as class decorators. When you’re using them on a class instead of a function, their effect might not be what you want. In the ...

It’s easy to index and slice NumPy arrays regardless of their dimension,meaning whether they are vectors or matrices. 索引和切片NumPy数组很容易,不管它们的维数如何,也就是说它们是向量还是矩阵。 With one-dimension arrays, we can index a given element by its position, keeping in mind that indice...
The difference is that it transforms the given amount to be negative. Therefore, no matter if the user sends a positive or a negative value, we will always store it as negative to facilitate calculations. Serializing and Deserializing Objects with Marshmallow With the Transaction superclass and...
