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 } …….. }
