def gettext():  #賦予txt哈姆雷特**-全英文小寫-全符號變空格-返回txt

txt = open('hamlet.txt','r').read()#注意文字的路徑
txt = txt.lower()#文字字元全部轉變為小寫字母
for ch in '!"#$%&()*+,-./:;<=>?@[\\]^_`~':
txt = txt.replace(ch," ") #使用空格字元替換掉文字中所有特殊字元
return txt
hamlettxt = gettext() #呼叫函式
words = hamlettxt.split()#以空字元做列表返回
counts = {}#建立乙個空字典
for word in words:
counts[word] = counts.get(word,0) + 1#get不到word就建立word為下標的值0+1，如果get到了就在word的值上加1，然後更新字典
items = list(counts.items())#字典的鍵值對變成列表
items.sort(key=lambda x:x[1],reverse=true)#以出現次數為標準排列，從大到小
for i in range(10):
word,count = items[i]
print(','.format(word,count))
