文本代码如下：

girl='''Remembering me, Discover and see All over the world, She's known as a girl To those who a free, The mind shall be key Forgotten as the past 'Cause history will last

God is a girl, Wherever you are, Do you believe it, can you recieve it? God is a girl, Whatever you say, Do you believe it, can you recieve it? God is a girl.'''

实现代码如下：

fo=open('daili.txt','r')
girl=fo.read()
girl='''Remembering me, Discover and see All over the world, She's known as a girl To those who a free, The mind shall be key Forgotten as the past 'Cause history will last

God is a girl, Wherever you are, Do you believe it, can you recieve it? God is a girl, Whatever you say, Do you believe it, can you recieve it? God is a girl.'''
exc={'','a','the','and','is','as','you','me','do'}

girl=girl.lower()
for i in ',?': 
 girl=girl.replace(i,' ')
words=girl.split(' ')
print('歌词：
',words)

dict={}
keys=set(words)
keys=keys-exc
print('最终单词:
',keys)


for i in words:
 dict[i]=words.count(i)
print('统计单词结果：
',dict)


dai=list(dict.items())
dai.sort(key=lambda x:x[1],reverse=True)
print('排序结果：
')


for i in range(20):
 print(dai[i])

fo.close()

程序结果如下：
