Python Forum

Hello, I am just starting to learn Python with the Python 3.5.2 version. I am supposed to start with a really easy task, renaming all the files in a folder. (Taking out the numbers out of the filenames.)

But I always get a Syntax-Error message (Invalid Syntax). Can someone please help me? I don't know what is wrong!

line 13: os apparently is a syntax error

import os

def rename_files():
    #(1) get file names form a folder
    file_list = os.listdir(r"C:\Users\harley\Documents\Python\Introduction\rename")
    #print(file_list)
    saved_path = os.getcwd()
    print("Current Wokring Directory is", saved_path)
    os.chdir(r"C:\Users\harley\Documents\Python\Introduction\rename")
    #(2) for each file, rename filename
    for file_name in file_list:
        os.rename(file_name, filename.translate("0123456789")
    os.chdir(saved_path)

rename_files()

Show us the whole traceback, please.

You missed a close-paren on line 12.

Missing parenthese in line 12.
Like this.

os.rename(file_name, filename.translate("0123456789"))

Hello!
In Python 3 str.translate() works a bit different.

In [1]: file_name = '0012ow32jioo123.hh1'

In [2]: table = {}

In [3]: for key in range(10):
   ...:     table[ord(str(key))] = None
   ...:     

In [4]: table
Out[4]: 
{48: None,
 49: None,
 50: None,
 51: None,
 52: None,
 53: None,
 54: None,
 55: None,
 56: None,
 57: None}

In [5]: new_file = file_name.translate(table)

In [6]: new_file
Out[6]: 'owjioo.hh'

I suppose you want to do this on the base name of the file not to an extension too. As you see is 'hh' now. This will ruin your mp3 collection
