This article example describes Python read English files and record the number of times each word appears after the descending output. Shared for your reference, as follows:
Periods, commas and exclamation points that appear in the text are treated accordingly
sortedSort Function Usage:
on the basis ofvalueThe values are listed in descending order:
sorted((),key=lambda k:k[1],reverse=True)
on the basis ofvalueThe values are sorted in ascending order:
sorted((),key=lambda k:k[1],reverse=False)
or
sorted((),key=lambda k:k[1])
on the basis ofkeyThe values are listed in descending order:
sorted((),key=lambda k:k[0],reverse=True)
on the basis ofkeyThe values are listed in ascending order:
sorted((),key=lambda k:k[0])
or
sorted((),key=lambda k:k[0],reverse=False)
Python Example:
# -*- coding:utf-8 -*-
#! python2
file_object=open("")
dict={}
for line in file_object:
line=(","," ")
line=("."," ")
line=("!"," ")
strs= ();
for str in strs:
if dict.has_key(str):
dict[str]+=1
else:
dict[str]=1
result=sorted((),key=lambda k:k[1],reverse=True)
print result

We are busy all day, like swarms of flies without souls, noisy, restless, unable to hear the voices of the soul. As time goes by, childhood away, we grew up, years away a lot of memories, once have also eroded the bottom of the childish innocence, we regardless of the shackles of mind, indulge in the world buckish, focus on the beneficial principle, we have lost themselves.
