Rename files with numbers

[dudufigueiredo]

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
So I need to change the file number to "The Beatles -"
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 - ', ...)
and Capitalize the name.
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.

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...

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
thousands?) of utilities in existence that do this and much more.

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 ??

[Dudu Figueiredo]

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

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...

def renme(artist, track): .... l1 = artist.title(). split()
.... l2 = track.title().s plit()[1:]
.... return "_".join(l1 + l2)
.... fn '01 - some title.mp3' renme("the beatles", fn) 'The_Beatles_-_Some_Title.Mp3 '
Or, if you are really insane... <G>
fn '01 - some title.mp3' "_".join("t he beatles".title( ).split() + fn.title().spli t()[1:]) 'The_Beatles_-_Some_Title.Mp3 '
