Join multiple sets with theunion()method: set1 = {"a","b","c"} set2 = {1,2,3} set3 = {"John","Elena"} set4 = {"apple","bananas","cherry"} myset = set1.union(set2, set3, set4) print(myset) Try it Yourself » ...
Sets cannot have two items with the same value. Example Duplicate values will be ignored: thisset = {"apple","banana","cherry","apple"} print(thisset) Try it Yourself » Note:The valuesTrueand1are considered the same value in sets, and are treated as duplicates: ...
set 集合也属于数据结构,它是一个 无序 且不重复 的元素序列。可以使用大括号 { } 或者set() 函数创建集合,注意:创建一个空集合必须用 set() 而不是 { },因为 { } 是用来创建一个空字典。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 str = 'Hello World!' print str[2:5] # 输出字符...
