Python 3x - Remove numbers from file names

import os

def rename_files():
    # (1) get file names from a folder
    file_list = os.listdir(r"C:\Users\USEER\Desktop\Udacity\Udacity - Programming Foundation with Python\Project\prank\prank")

    # print(file_list)
    saved_path = os.getcwd()
    print("Current Working Directory is " + saved_path)
    os.chdir(r"C:\Users\USEER\Desktop\Udacity\Udacity - Programming Foundation with Python\Project\prank\prank")

    # (2) for each file, rename file name
    for file_name in file_list:
        print("Old Name - " + file_name)
        print("New Name - " + file_name.translate("0123456789"))
        os.rename(file_name, file_name.translate("0123456789"))
    os.chdir(saved_path)

rename_files()

The code above doesn't rename the file by removing the integers. Can anyone help? (Python 3x)

Here is one way of renaming files.

  1. Use os.renames to rename the files
  2. Use file_name.strip("0123456789") to remove numbers

Code is given below:

import os
def file_rename():
    name_list=os.listdir(r"C:\python\prank")
    print(name_list)
    saved_path=os.getcwd()
    print("Current working directory is"+saved_path)
    os.chdir(r"C:\python\prank")

    for file_name in name_list:
        print("old name"+file_name)
        print("new name"+file_name.strip("0123456789"))
        os.renames(file_name,file_name.strip("0123456789"))
    os.chdir(saved_path)

file_rename()

In Python 3 the String.translate is gone. Therefore you need to use the str.translate. It needs 'str.maketrans' which normally creates a translation table with the first two arguments supplied(not needed in this example), the third argument supplies the characters to be stripped.

This line should have the desired effect ...

os.rename(file_name, file_name.translate(str.maketrans('','','0123456789'))

Previous suggestions used .strip() however in this case as the numbers are mixed in with the filenames (not before or after) I believe it would not work, another used Regular Expressions which is perfectly valid, however within the context of this particular Udacity course translate was the suggested solution.

Here are the docs for maketrans : [https://docs.python.org/3/library/stdtypes.html#str.maketrans][1]

Another way to do this without import re. Instead of utilizing the .translate, use the .strip.

os.rename(file_name, file_name.strip('0123456789'))

Another observation is that your code wont read the new file name after changing it. At the top of your code you are reading file names and saving those name in file_list

# (1) get file names from a folder
file_list = os.listdir(r"C:\Users\USEER\Desktop\Udacity\Udacity - Programming Foundation with Python\Project\prank\prank")

In the for loop, where you are changing the name of each file, YOU ARE NOT reading the new file's name. You need to do something like this.

# (2) for each file, rename file name
for file_name in file_list:
    print("Old Name - " + file_name)
    os.rename(file_name, file_name.strip("0123456789"))

# (3) read file's name again... 'file_list' has old names
new_file_list = os.listdir(r"C:\Users\USEER\Desktop\Udacity\Udacity - Programming Foundation with Python\Project\prank\prank")
for file_name in new_file_list:
    print("New file's name: " + new_file_name)

os.chdir(saved_path)

The problem is in your translate function that doesn't do anything. There are better options available, but if your want to use translate then the proper syntax is:

#!/usr/bin/env python2

import string
new_name = string.translate(file_name, None, "0123456789")
