python读取文件名并改名字的实例

第一版，能实现，但最后发现文件的顺序改变了：

import os

def reename():
nm=1
pathh="/home/huangyaya/file/image/pic/chips"
filelist=os.listdir(pathh)
for files in filelist:
 Olddir=os.path.join(pathh,files)
 filename=os.path.splitext(files)[0]
 filetype=os.path.splitext(files)[1]
 Newdir=os.path.join(pathh,str(nm)+'.'+filetype)
 os.rename(Olddir,Newdir)
 nm+=1

reename()

新的

import os
import pdb

#dir_ = os.getcwd()
#dir_ += '/cips'
#os.chdir(dir_)

path_A = "/home/huangyaya/file/image/pic/wine"
path_B = "/home/huangyaya/file/image/pic/wine_output"
file_number = 1
num = 0
A_list = os.listdir(path_A)
B_list = os.listdir(path_B)
A_list_num = 0
B_list_num = 0

for A_str in A_list:
A_str_front = A_str[:-4]
B_str = A_str_front + '.xml'

os.rename(path_A + '/' + A_str,str(file_number) + '.jpg')
os.rename(path_B + '/' + A_str_front + '.xml',str(file_number) + '.xml')

file_number += 1
