both operands must be sets. The.union()method, on the other hand, will take any iterable as an argument, convert it to a set, and then perform the union.
To perform set operations like s-t, both s and t need to be sets. However you can do the method equivalents even if t is any iterable, for example s.difference(l), where l is a list. (4)子字典:dict 为dict对象列出的平均情况时间假设对象的哈希函数足够强大,以至于不常见冲突。 平均情况...

6. 集合(Sets) 集合是由唯一元素组成的无序集合,可以进行数学上的集合运算,如并集、交集和差集。以下是一个集合对象的示例代码: fruits={"apple","banana","orange"}# 集合的操作fruits.add("grape")# 添加元素fruits.remove("banana")# 删除元素# 集合的运算fruits2={"apple","pear","grape"}union=fruit...
