    person = []
    for i in range(1, 4):
    person.append(i)
    print 'person:%s' % person
    index = 0
    while len(person) > 1:
    removelist = []
    for item in person:
    index += 1
    if index == 3:
    removelist.append(item)
    index = 0
    print 'removelist:%s' % removelist
    for item in removelist:
    person.remove(item)

    print 'current person list:%s' % person
print 'current removelist:%s' % removelist

    print 'left person list:%s' % person

    java 版：
    import java.util.ArrayList;
    import java.util.List;

    public class TestShushu {

    public static void main(String[] args) {
    // TODO Auto-generated method stub
    List<Integer> list = new ArrayList<Integer>();
    for(int i=1;i<4;i++) {
        list.add(i);
    }
    System.out.println(list);

    int index = 0;
    while(list.size() > 1) {
        List<Integer> removelist = new ArrayList<Integer>();
        for(int i: list) {
            index ++;
            if(index == 3) {
                removelist.add(i);
                //System.out.println(removelist);
                index = 0;
            }
        }
        System.out.println("要删除的数组" + removelist);
        list.removeAll(removelist);
        System.out.println("当前数组元素：" + list);

    }
    System.out.println("最后留下的那个编号：" + list);

}

    }
