使用集合的交集函数。a_set.intersection（b_set）如果至少有一个元素是公共的，则返回正整数，否则返回0。因此，我们在set_a中插入a，在set_b中插入b，然后检查a_set.intersection（b_set），并根据值返回。def common_member(a, b):a_set = set(a)b_set = set(b)if len(a_set.intersection(b_set)...

If two lists have intersection, then their last nodes must be the same one. So when pA/pB reaches the end of a list, record the last element of A/B respectively. If the two last elements are not the same one, then the two lists have no intersections. Analysis written by@stellari....
``intersect_set = set1.intersection(set2)``语句实现了取集合交集的操作。

Python Intersection and Union Python provides built-in functions to find the intersection and union of two sets or lists. These functions areintersectionandunion. In this article, we will explore these functions and see how they can be used in various scenarios. ...
The intersection, union, difference, and symmetric difference of two lists; The sorting method of the list. 1. Delete an element in the list To delete an element in the list, you can usedelandremove. del is to delete elements according to subscripts, and remove is to delete elements accord...

The value of thekeyparameter should be a function that takes a single argument and returns a key to use for sorting purposes. This technique is fast because the key function is called exactly once for each input record.key参数的值应该是一个采用单个参数并返回用于排序目的键的函数。这种技术之所以...
