Renaming multiple files in a directory using Python

问题

I'm trying to rename multiple files in a directory using this Python script:

import os
path = '/Users/myName/Desktop/directory'
files = os.listdir(path)
i = 1

for file in files:
    os.rename(file, str(i)+'.jpg')
    i = i+1

When I run this script, I get the following error:

Traceback (most recent call last):
  File "rename.py", line 7, in <module>
    os.rename(file, str(i)+'.jpg')
OSError: [Errno 2] No such file or directory

Why is that? How can I solve this issue?

Thanks.

回答1:

You are not giving the whole path while renaming, do it like this:

import os
path = '/Users/myName/Desktop/directory'
files = os.listdir(path)


for index, file in enumerate(files):
    os.rename(os.path.join(path, file), os.path.join(path, ''.join([str(index), '.jpg'])))

Edit: Thanks to tavo, The first solution would move the file to the current directory, fixed that.

You have to make this path as a current working directory first. simple enough. rest of the code has no errors.

to make it current working directory:

os.chdir(path)

As per @daniel's comment, os.listdir() returns just the filenames and not the full path of the file. Use os.path.join(path, file) to get the full path and rename that.

import os
path = 'C:\\Users\\Admin\\Desktop\\Jayesh'
files = os.listdir(path)
for file in files:
   os.rename(os.path.join(path, file), os.path.join(path, 'xyz_' + file + '.csv'))

If your files are renaming in random manner then you have to sort the files in the directory first. The given code first sort then rename the files.

import os
import re
path = 'target_folder_directory'
files = os.listdir(path)
files.sort(key=lambda var:[int(x) if x.isdigit() else x for x in re.findall(r'[^0-9]|[0-9]+', var)])
for i, file in enumerate(files):
    os.rename(path + file, path + "{}".format(i)+".jpg")

Just playing with the accepted answer define the path variable and list:

path = "/Your/path/to/folder/"
files = os.listdir(path)

and then loop over that list:

for index, file in enumerate(files):
    #print (file)
    os.rename(path+file, path +'file_' + str(index)+ '.jpg')

or loop over same way with one line as python list comprehension :

[os.rename(path+file, path +'jog_' + str(index)+ '.jpg')  for index, file in enumerate(files)]

I think the first is more readable, in the second the first part of the loop is just the second part of the list comprehension

I worked on a quick and flexible script to take care of displaying differences, asking for confirmations, and renaming. If you need a working solution, you can copy this script and place it in the folder of which you want to rename files. https://gist.github.com/aljgom/81e8e4ca9584b481523271b8725448b8

It renames files in current directory by passing "rename functions", each function can take care of a change. Then determines the changes that each function will make and displays the differences using colors, and asks for confirmation to perform the changes. Works on pycharm, haven't tested it in different consoles
