Renaming multiple files in a directory using Python

import os from os import path import shutil Source_Path = 'E:\Binayak\deep_learning\Datasets\Class_2' Destination = 'E:\Binayak\deep_learning\Datasets\Class_2_Dest' #dst_folder = os.mkdir(Destination) def main(): for count, filename in enumerate(os.listdir(Source_Path)): dst = "Class_2_" + str(count) + ".jpg" # rename all the files os.rename(os.path.join(Source_Path, filename), os.path.join(Destination, dst)) # Driver Code if __name__ == '__main__': main() 

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')) 

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

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") 

This works for me and by increasing the index by 1 we can number the dataset.

import os path = '/Users/myName/Desktop/directory' files = os.listdir(path) index=1 for index, file in enumerate(files): os.rename(os.path.join(path, file),os.path.join(path,''.join([str(index),'.jpg']))) index = index+1 

But if your current image name start with a number this will not work.

I wrote a quick and flexible script for renaming files, if you want a working solution without reinventing the wheel.

It renames files in the current directory by passing replacement functions.

Each function specifies a change you want done to all the matching file names. The code will determine the changes that will be done, and displays the differences it would generate using colors, and asks for confirmation to perform the changes.

You can find the source code here, and place it in the folder of which you want to rename files https://gist.github.com/aljgom/81e8e4ca9584b481523271b8725448b8

It works in pycharm, I haven't tested it in other consoles

The interaction will look something like this, after defining a few replacement functions

when it's running the first one, it would show all the differences from the files matching in the directory, and you can confirm to make the replacements or no, like this
