Python script recursively rename all files in folder and subfolders

Question

Hi I have a number of different files that need to be renamed to something else. I got this far but I want to have it so that I can have many items to replace and their corresponding replacements rather than type each one out, run the code then retype it again.

UPDATE* Also I need the rename to only change part of the file not the whole thing so if there was a “Cat5e_1mBend1bottom50m2mBend2top-Aqeoiu31” it would just change it to “‘Cat5e50m1mBED_50m2mBE2U-Aqeoiu31”

import os, glob

#searches for roots, directory and files
for root,dirs, files in os.walk(r"H:My DocumentsCrossTalk\"):
   for f in files:
       if f == "Cat5e_1mBend1bottom50m2mBend2top":#string you want to rename
          try:
             os.rename('Cat5e_1mBend1bottom50m2mBend2top', 'Cat5e50m1mBED_50m2mBE2U'))
          except FileNotFoundError, e:
             print(str(e))

Answer 1

The first thing you’d need is a dictionary for the replacements, then a small change in your code:

import os, glob

name_map = {
     "Cat5e_1mBend1bottom50m2mBend2top": 'Cat5e50m1mBED_50m2mBE2U'
}

#searches for roots, directory and files
for root,dirs,files in os.walk(r"H:My DocumentsCrossTalk"):
   for f in files:
       if f in name_map:
          try:
             os.rename(os.path.join(root, f), os.path.join(root, name_map[f]))
          except FileNotFoundError, e:
          #except FileNotFoundError as e:  # python 3
             print(str(e))

In the name_map, the key (string to the left of “:“) is the name of the file in your filesystem, and the value (string to the right of the “:“) is the name you want to use.

Is this wath you want?

import os, glob
#searches for roots, directory and files
#Path
p=r"C:\Users\joao.limberger\Documents\Nova Pasta"
# rename arquivo1.txt to arquivo33.txt and arquivo2.txt to arquivo44.txt
renames={"arquivo1.txt":"arquivo33.txt","arquivo2.txt":"arquivo44.txt"}
for root,dirs,files in os.walk(p):
   for f in files:
      if f in renames.keys():#string you want to rename
         try:
            os.rename(os.path.join(root , f), os.path.join(root , renames[f]))
            print("Renaming ",f,"to",renames[f])
         except FileNotFoundError as e:
            print(str(e))

Check if this is what you want!!!

import os, glob
#searches for roots, directory and files
#Python 2.7
#Path 
p=r"C:\Users\joao.limberger\Documents\Nova Pasta"
#  if the substring in the key exists in the filename, replace the substring 
#   from the value of the key
#   if the key is "o1" and the value is "oPrinc1" and the filename is
#  arquivo1.txt ... The filename will be renamed to "arquivoPrinc1.txt"
renames={"o1":"oPrinc1","oldSubs":"newSubs"}
for root,dirs,files in os.walk(p):
    for f in files:
        for r in renames:
            if r in f:
                newFile = f.replace(r,renames[r],1)
                try:
                    os.rename(os.path.join(root , f), os.path.join(root , newFile))
                    print "Renaming ",f,"to",newFile
                except FileNotFoundError , e:
                    print str(e)
