Batch Renaming of Files in a Directory

Question

Is there an easy way to rename a group of files already contained in a directory  using Python   Example    I have a directory full of   doc files and I want to rename them in a consistent way      X doc -   new X  doc       Y doc -   new Y  doc

as to me in my directory I have multiple subdir, each subdir has lots of images I want to change all the subdir images to 1.jpg ~ n.jpg

def batch_rename():
    base_dir = 'F:/ad_samples/test_samples/'
    sub_dir_list = glob.glob(base_dir + '*')
    # print sub_dir_list # like that ['F:/dir1', 'F:/dir2']
    for dir_item in sub_dir_list:
        files = glob.glob(dir_item + '/*.jpg')
        i = 0
        for f in files:
            os.rename(f, os.path.join(dir_item, str(i) + '.jpg'))
            i += 1

I had a similar problem  but I wanted to append text to the beginning of the file name of all files in a directory and used a similar method  See example below   folder   r R  mystuff GIS Projects Website 2017 PDF   import os   for root  dirs  filenames in os walk folder     for filename in filenames        fullpath   os path join root  filename        filename split   os path splitext filename    filename will be filename split 0  and extension will be filename split 1       print fullpath     print filename split 0      print filename split 1      os rename os path join root  filename   os path join root   NewText 2017     filename split 0    filename split 1

Such renaming is quite easy  for example with os and glob modules   import glob  os  def rename dir  pattern  titlePattern       for pathAndFilename in glob iglob os path join dir  pattern            title  ext   os path splitext os path basename pathAndFilename           os rename pathAndFilename                     os path join dir  titlePattern   title   ext     You could then use it in your example like this   rename r c  temp xx   r   doc   r new  s      The above example will convert all   doc files in c  temp xx dir to new  s  doc  where  s is the previous base name of the file  without extension

If you don t mind using regular expressions  then this function would give you much power in renaming files   import re  glob  os  def renamer files  pattern  replacement       for pathname in glob glob files           basename  os path basename pathname          new filename  re sub pattern  replacement  basename          if new filename    basename              os rename                pathname                os path join os path dirname pathname   new filename     So in your example  you could do  assuming it s the current directory where the files are    renamer    doc   r        doc    r new  1  doc     but you could also roll back to the initial filenames   renamer    doc   r  new          doc   r  1 doc     and more

I ve written a python script on my own  It takes as arguments the path of the directory in which the files are present and the naming pattern that you want to use  However  it renames by attaching an incremental number  1  2  3 and so on  to the naming pattern you give   import os import sys    checking whether path and filename are given  if len sys argv     3      print  Usage   python rename py  lt path gt   lt new name extension gt       sys exit      splitting name and extension  name   sys argv 2  split      if len name   lt  2      name append     else      name 1       s   name 1     to name starting from 1 to number of files  count   1    creating a new folder in which the renamed files will be stored  s     s pic folder    sys argv 1  try      os mkdir s  except OSError        if pic folder is already present  use it      pass  try      for x in os walk sys argv 1            for y in x 2                 creating the rename pattern              s     spic folder  s s s    x 0   name 0   count  name 1                 getting the original path of the file to be renamed              z   os path join x 0  y                renaming              os rename z  s                incrementing the count              count   count   1 except OSError      pass   Hope this works for you
