从文件夹中的所有文件名中删除数字

Question

I am trying to remove all numbers from all filenames for files in a folder:

import os
import re
infolder = r'E:/folder/test'
def file_rename():
    name_list=os.listdir(infolder)
    print(name_list)
    saved_path=os.getcwd()
    print("Current working directory is"+saved_path)
    os.chdir(infolder)

    for file_name in name_list:
        print("old name"+file_name)
        print("new name"+re.sub('[0-9]', '', file_name))
        os.renames(file_name,file_name.strip("0123456789"))
    os.chdir(saved_path)

file_rename()

It's correctly printing the new filenames but is not actually changing the files names in the folder.

Answer 1

Your code shows that you are printing something different to what you are actually doing.

print("new name"+re.sub('[0-9]', '', file_name))

If this is printing the correct content, then your os.renames function should look as follows

os.renames(file_name,re.sub('[0-9]', '', file_name))

Answer 2

str.strip() function removes leading and trailing characters only.

try using

os.renames(file_name, re.sub('[0-9]', '', file_name))

instead.
