list =[{'級別':1,'num':'a'},
{'級別':1,'num':'ab'},
{'級別':1,'num':'aasdf'},
{'級別':2,'num':'as'},
{'級別':2,'num':'sda'},
{'級別':3,'num':'asd'},
{'級別':2,'num':'sdwqw'},
{'級別':1,'num':'dqwee'},
{'級別':1,'num':'sre'},
{'級別':2,'num':'sxzxc'},
{'級別':2,'num':'sxzasdxc'},
{'級別':3,'num':'sxzsxc'},
{'級別':1,'num':'sxasdzxc'}]
要求級別為1并以'aa'開頭的元素，到下一個級別為1之間的元素全部洗掉
結果是這樣的
[{'級別':1,'num':'a'},
{'級別':1,'num':'ab'},
{'級別':1,'num':'aasdf'},
{'級別':1,'num':'dqwee'},
{'級別':1,'num':'sre'},
{'級別':2,'num':'sxzxc'},
{'級別':2,'num':'sxzasdxc'},
{'級別':3,'num':'sxzsxc'},
{'級別':1,'num':'sxasdzxc'}]
