python编程：统计文件中单词出现次数

f=open("2.txt",'r')

ll=f.read()

'''将空格都取代为逗号，方便后面的split（）'''

ll=ll.replace(" ",',')

'''防止由于文档编辑不规范出现双逗号的情况'''

ll=ll.replace(",,",',')

l=ll.split("\n")

rows=[]

dic={}

for i in l:

row=i.split(",")

rows.append(row)

for ii in rows:

for each in ii:

if each in dic:

dic[each]=dic[each]+1

else:

dic[each]=1

#输出所有的排序：

print(sorted(dic.items(),key=lambda x:x[1],reverse=True))

'''只输出最大的值'''

HighValue=0

HighKey=None

for each in dic:

if dic[each]>HighValue:

HighValue=dic[each]

HighKey=each

print(HighKey,HighValue)
