函數的形式

def modifyip(tfile,sstr,rstr):

    try:

        lines=open(tfile,'r').readlines()

        flen=len(lines)-1

        for i in range(flen):

            if sstr in lines[i]:

                lines[i]=lines[i].replace(sstr,rstr)

        open(tfile,'w').writelines(lines)

        

    except Exception,e:

        print e

modifyip('a.txt','a','A')把文件中的全部小a換成A

直接修改某一行

#!/usr/bin/python

import sys,os

f=open('hi.txt','r+')
flist=f.readlines()
flist[4]='hi\n'
f=open('hi.txt','w+')
f.writelines(flist)
