Python翻译功能不起作用

Question

I have this following simple function which I try to replace any numeric values of a file name inside a given folder. This is what I have so far

import os

def decode_message():

    #this is stage one
    file_list = os.listdir(r"C:\TestFolder");
    #this is stage two
    print(file_list);
    os.chdir(r"C:\TestFolder")
    saved_path = os.getcwd();
    print("Current Working Directory : "+saved_path)
    for file_name in file_list:
            print("Old File Name : "+file_name);
            os.rename(file_name,file_name.translate(None,"0123456789"))
decode_message()

This is working up to the point where I can list the file names as shown below

But once i use the translate option it gives the following error

Can Anyone help?

Answer 1

Solution 1: Update your python version : You're on python 2.4 which is about 12 years old by now. If you update to Python 2.7 your translate would work. I don't have a python 2.4 version available, nor can I find the documentation. Also: have a look at this question and the answers. It is exactly the same question

Solution 2: Replace the numeric character with something else

eg

import re
os.rename(file_name, re.sub('\d+', '', file_name))

or

file_name2 = "".join(ch for ch in file_name if not ch.isdigit())
os.rename(file_name, file_name2)

Answer 2

Seems as if you're looking at only files that begin with a digit. However some files begin with . , like the .DS_Store file, and your program is getting stuck there as it not taking into consideration any file that does not begin with a digit.

Answer 3

file_name.translate(None,"0123456789")

You can`t give None as translation table.
