python如何遍历set
1、利用迭代器进行迭代遍历:
Set<Object> sets = new HashSet<Object>();Iterator<Object> it = set.iterator();
while (it.hasNext()) {
String str = (String)it.next();
System.out.println(str);
}
2、for循环遍历:
for (String str : sets) {System.out.println(str);
}
3、foreach循环遍历:
Set<Object> set = new HashSet<Object>();for (Object obj: sets) {
if(obj instanceof Integer){
int aa= (Integer)obj;
}else if(obj instanceof String){
String aa = (String)obj
}
……..
}
