Rename files with numbers

[dudufigueiredo@gmail.com]

I have one folder containing mp3 files, the folder is:
C:\My Shared Folder\Rubber Soul

And the files are:
01 drive my car.mp3
02 norwegian wood.mp3
03 you won't see me.mp3
04 nowhere man.mp3
..
..
..

I'm trying to rename files to:
The Beatles - Drive My Car.mp3
The Beatles - Norwegian Wood.mp3
The Beatles - You Won't See Me.mp3
The Beatles - Nowhere Man.mp3
..
..
..

So I need to change the file number to "The Beatles -" and Capitalize
the name.
I was trying to create a function and using glob and rename, but i had
no sucsses...
Could somebody help me please,
Since now, thanks...

My first suggestion is that you make better changes while you're
taking the effort to rename. I.e., don't use spaces or apostrophes
(or other shell-unfriendly characters) in file names (though some
might disagree with me on this religious issue). So for your case a
more parse-able/useful translation might be:

The_Beatles_-_You_Wont_See_M e.mp3
[color=blue]
> So I need to change the file number to "The Beatles -"[/color]

You'll probably want to use "re" for this. In a loop over
your glob'd files, something like:

re.sub(r'^\d\d\ s', r'The Beatles - ', ...)
[color=blue]
> and Capitalize the name.[/color]

If you avoid the apostrophe, then 'you wont see me'.title() will do
the Right Thing.

You should post the solution you've attempted to write if you want help
fixing it.

Re: Rename files with numbers

Ok, so the function simplifyed without loops:

def renamer(folder, band):
archive = #file to transform
rest = archive[3:]
print band + " -",rest.capitali ze()


obs: the file names came this way(with spaces or apostrophes) from the
cd i imported.

So remove them first. Here's a possible solution::

#! /usr/bin/env python

import glob, os.path

uglies = glob.glob("*.mp 3")
print 'uglies:', uglies
pretties = []

for ugly in uglies:
song, ext = os.path.splitex t(ugly)
song = song.replace("' ", "")
song = song.replace(" ", "_")
song = song.title()
song = "The_Beatle s_-_" + song[3:]
song_ext = song + ext
pretties.append (song_ext)

print 'pretties:', pretties

# rename uglies to pretties...

Re: Rename files with numbers

Micah, thanks a lot,
but my focus is to learn how to acess a folder and rename all files in
this folder.

Somyhing like this:
def renamer(folder, band):
folder = #place to act
archive = #file to transform
rest = archive[3:]
print band + " -", rest.capitalize ()

And than just do this:

renamer('C:\My Shared Folder\Rubber Soul', 'The Beatles')

And than pyhton alter all files in my folder. Is it possible?

I'm a beginer, for now, i just want to let the spaces and apostrophes
as they are...

This is a little more flexible than my last post, and it does the
whole job::

#! /usr/bin/env python

import glob, os, string

def fix_ugly_song_n ames(songdir, band, spacerepl='_'):
"""Rename an ugly MP3 file name to a beautified shell-correct
name. Only works for files named like "03 song name.mp3".
Use `spacerepl` to alter space replacement character.
WARNING: no error-handling!
"""
# Begin working in specified `songdir`.
os.chdir(songdi r)
# Shell-unfriendly characters made into a string.
badchars = ''.join( set(string.punc tuation) - set('-_+.~') )
# Identity table for later translation (removal of `badchars`).
tbl = string.maketran s('', '')
# MP3 files in `songdir` having ugly characters.
uglies = glob.glob("*.mp 3")
# Make some step-by-step changes to build `pretties` list.
pretties = []
for ugly in uglies:
song, ext = os.path.splitex t(ugly)
song = song.translate( tbl, badchars)
song = song.replace(" ", spacerepl)
song = song.title()
song = band+spacerepl+ "-"+spacerepl+son g[3:]
songext = song + ext
pretties.append (songext)
# Rename each file from ugly to pretty.
for ugly, pretty in zip(uglies, pretties):
if __debug__:
print ugly, '-->', pretty
else:
os.rename(ugly, pretty)

So for you to use spaces, just call with something like this::

fix_ugly_song_n ames('/var/mp3/pop/The_Beatles/Rubber_Soul',
'The Beatles',
spacerepl=' ')

I used the __debug__ gate to allow you to just see what it will do::

$ ls -1
01 drive my car.mp3
02 norwegian wood.mp3
03 you won't see me.mp3
04 nowhere man.mp3
mvmp3.py
$ python ./mvmp3.py
01 drive my car.mp3 --> The Beatles - Drive My Car.mp3
02 norwegian wood.mp3 --> The Beatles - Norwegian Wood.mp3
03 you won't see me.mp3 --> The Beatles - You Wont See Me.mp3
04 nowhere man.mp3 --> The Beatles - Nowhere Man.mp3

And then to actually do it with the non-__debug__ path::

$ python -O ./mvmp3.py
$ ls -1
mvmp3.py
The Beatles - Drive My Car.mp3
The Beatles - Norwegian Wood.mp3
The Beatles - Nowhere Man.mp3
The Beatles - You Wont See Me.mp3

If you want to keep the `badchars` in the file names, then you will
have to do *more* work since `song.title()` won't be able to do the
work for you.

Now I need to go beautify my collection. :-)

While a fun exercise, there are probably already dozens (or

Re: Rename files with numbers

Micah, thanks a lot, nice script!
But its not completly working, i ran this:

fix_ugly_song_n ames('C:\My Shared Folder\Rubber Soul', 'The
Beatles', spacerepl=' ')

And the shell prints this:

01 drive my car.mp3 --> The Beatles - Drive My Car.mp3
02 norwegian wood (this bird has flo).mp3 --> The Beatles -
Norwegian Wood This Bird Has Flo.mp3
03 you won't see me.mp3 --> The Beatles - You Wont See Me.mp3
04 nowhere man.mp3 --> The Beatles - Nowhere Man.mp3
05 think for yourself.mp3 --> The Beatles - Think For Yourself.mp3
06 the word.mp3 --> The Beatles - The Word.mp3
07 michelle.mp3 --> The Beatles - Michelle.mp3
08 what goes on.mp3 --> The Beatles - What Goes On.mp3
09 girl.mp3 --> The Beatles - Girl.mp3
10 i'm looking through you.mp3 --> The Beatles - Im Looking Through
You.mp3
11 in my life.mp3 --> The Beatles - In My Life.mp3
12 wait.mp3 --> The Beatles - Wait.mp3
13 if i needed someone.mp3 --> The Beatles - If I Needed
Someone.mp3
14 run for your life.mp3 --> The Beatles - Run For Your Life.mp3

But the files didn't change in the folder!
Is there something mising or i'm doing something worng ??

Oh, forget what i've just said, i didn't read the __debug__ part.
It worked perfectly =]

Fancy CD, in that case... Most of mine come in as track01, track02,
etc. It is only when the ripping software accesses a CDDB system that
real titles get assigned (and the track number is an option in the
current software I have).

However...

'The_Beatles_-_Some_Title.Mp3 '[color=blue][color=green][color=darkred]

Or, if you are really insane... <G>

Seconded. I initially considered writing a script to rename a huge pile of
MP3 files, but halfway through, I thought, "there's *got* to be a better
way". I found this app: http://www.softpointer.com/tr.htm

Bought it the next day. Holy crap, what a gigantic timesaver. It looks up
albums based on track lengths, downloads titles from freedb and Amazon,
does ID3 tagging, renaming, moves files into separate directories... I
busted through about 20 gigs of MP3s in three days. I kid you not.

If this is just a fun toy Python project, don't let me discourage you, but
if you have more than a handful of albums to rename, trust me. This
problem has been solved.

Here's a list of apps, including Tag&Rename, that can query freedb:

Re: Rename files with numbers

The best free app I've found for this is MusicBrainz [www.musicbrainz.com].

This has a huge database of obsessively correct details of albums
which can be formatted in anyway you choose. It can automatically
recognise which song an MP3 is!

This is a similar script I wrote to renumber files in sequential
order. It assumes that everything before the first underscore can be
replaced.

from path import path
import re

def renumberfiles(f ilesdir, startnum=1):
d = path(filesdir)
print d
x = startnum
for f in d.files():
fname = f.name.split('_ ', 1)
fname = str(x).zfill(2) + "_" + fname[-1]
fname = re.sub(r" ",r"_",fnam e)
fname = re.sub(r"__",r" _",fname)
x = x + 1
print f.name, "==>",
f.rename(f.pare nt + "\\" + fname)
print fname

As you can see, I use the path module rather than os.path. it's a
much more intuitive way of handling files.

Re: Rename files with numbers

I wrote a simpler script based in Micah Elliott's help, it's to add the
band name to mp3 files imported with iTunes:

import glob, os

def renamer_itunes( songdir, band):
""" Rename mp3 files imported from itunes, transformation:
Song Name.mp3 --> Artists - Song Name.mp3
"""
os.chdir(songdi r)
archives = glob.glob("*.mp 3")
pretties = []
for ugly in archives:
song, ext = os.path.splitex t(ugly)
song = song.title()
song = band + " - " + song
songext = song + ext
pretties.append (songext)
for ugly, pretty in zip(archives, pretties):
os.rename(ugly, pretty)

Just an exercise, I'm begining in Python now...
Thanks to every one that helped me, i'll bring more questions for you.
Sorry for my bad english, i'm Brazilian... !

File renaming recipe (was: Rename files with numbers)

I expanded my code from this thread to be a Cookbook recipe. It has
no specificity for MP3 renaming, but is generic to files with
shell-unfriendly names. It should usable as-posted if anyone needs to
cleanup a filesystem.

Any comments/improvements are appreciated.

Maybe you want to take a look at Jack
