Based on the properties of symmetric difference of sets, a symmetric difference operator for fuzzy sets is defined to be a continuous and associative binary operator on the closed unit interval with some boundary condition. Structures and properties of these operators are investigated in this paper....
请注意:union(), intersection(), difference() 和 symmetric_difference() 的非运算符(non-operator,就是形如 s.union()这样的)版本将会接受任何 iterable 作为参数。相反,它们的运算符版本(operator based counterparts)要求参数必须是 sets,如果都是set会报错。

2020, Fuzzy Sets and Systems Citation Excerpt : Symmetric difference operator is closely related to other topics of fuzzy concept as well as Indistinguishability [14] [15] [32], T-equaivalences [4] [20] [26], T-equalities [6] and T-partitions [5] [13]. Since the introduction of ...
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对集合内数据的操作。作为一个无序的集合,sets不记录元素位置或者插入点。因此,sets**不支持 indexing, slicing**, 或其它类序列(sequence-like)的操作。 集合用于包含一组无序的对象。要创建集合,可使用set()函数并像...
Recently V.I.Arnold have formulated a geometrical concept of monads and apply it to the study of difference operators on the sets of $\{0,1\}$-valued sequences of length $n$. In the present note we show particular examples of these monads and indicate one question arising here.关键词:...
To check if a specific element exists in a tuple, you can use the in operator in Python. The in operator returns True if the element is found in the tuple, and False otherwise. This allows you to easily perform membership tests on tuples. For instance, if you have a tuple of numbers...
The operatordifference_closed_contours_xldcalculates the difference of the regions enclosed by the contoursContoursandSub. The boundaries of this difference are returned inContoursDifference. If the individual input contours are not closed, they are closed automatically by connecting their start and end ...
