python批量复制并重命名文件

假设有一张图片，准备将其拷贝成多张（TXT里有多少个名字就将其拷贝成多少张）并对其命名，名字从一个TXT文本里读取（或者Excel表）。

#! /usr/bin/env python
# coding=utf-8
import os
import shutil
import time
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

def copy_and_rename(fpath_input, fpath_output):
for file in os.listdir(fpath_input):
#if os.path.splitext(file)[1] == ".jpg":
oldname = os.path.join(fpath_input, file)
newname_1 = os.path.join(fpath_output,
os.path.splitext(file)[0] + "_1.jpg")
newname_2 = os.path.join(fpath_output,
os.path.splitext(file)[0] + "_2.jpg")
newname_3 = os.path.join(fpath_output,
os.path.splitext(file)[0] + "_3.jpg")
#os.rename(oldname, newname)
shutil.copyfile(oldname, newname_1)
shutil.copyfile(oldname, newname_2)
shutil.copyfile(oldname, newname_3)

if __name__ == '__main__':
print('start ...')
t1 = time.time() * 1000
#time.sleep(1) #1s
fpath_input = "C:/Users/jack/Desktop/shopimg/0708/"
fpath_output = "C:/Users/jack/Desktop/shopimg/0708/"
copy_and_rename(fpath_input, fpath_output)
t2 = time.time() * 1000
print('take time:' + str(t2 - t1) + 'ms')
print('end.')
