song ='''
I'm a big big girl
in a big big world
It's not a big big thing if you leave me
but I do do feel 
that I too too will miss you much
miss you much...
I can see the first leaf falling
it's all yellow and nice
It's so very cold outside
like the way I'm feeling inside
I'm a big big girl
in a big big world
It's not a big big thing if you leave me
but I do do feel 
that I too too will miss you much
miss you much...
Outside it's now raining
and tears are falling from my eyes
why did it have to happen
why did it all have to end
I'm a big big girl
in a big big world
It's not a big big thing if you leave me
but I do do feel
that I too too will miss you much
miss you much...
I have your arms around me ooooh like fire
but when I open my eyes
you're gone...
I'm a big big girl
in a big big world
It's not a big big thing if you leave me
but I do do feel
that I too too will miss you much
miss you much...
I'm a big big girl
in a big big world
It's not a big big thing if you leave me
but I do feel I will miss you much
miss you much...'''

最终显示结果

心得：上网学了新的知识点，如sorted,也强化了字典的认识

老师给的顺序并不一定是操作的顺序，可以先排除语法型词汇再去排序，这样效果更佳
