intersection(another_set) # 差集 difference_set = my_set.difference(another_set) 集合的遍历 可以使用循环来遍历集合中的每个元素。 for item in my_set: print(item) 七.数据类型判断和转换 数据类型查看 要查看一个变量的数据类型,可以使用type()函数。 示例: x = 5 print(type(x)) # 输出: <...

Theupdate()method inserts all items from one set into another. Theupdate()changes the original set, and does not return a new set. Example Theupdate()method inserts the items in set2 into set1: set1 = {"a","b","c"} set2 = {1,2,3} ...
