Re: Path / Listing and os.walk problem.
So I found a way to do it, maybe some people could be interested:
listNames = []
for n in names:
listNames.append('_'.join(n.split('_')[:-1]))
#It will cut the last part of the file name convention
listNames = list(set(listNames)) #we Delete duplicates from the list, like
this we only have what we are interested in
for e in listNames: #Juste to check.
print e

Re: Path / Listing and os.walk problem.
Hey ! Thank you guys !
It help me a lot !
@Dennis (Gomes): Thanks ! I tried it it worked well but list me the whole
files :P (and finally crashed python...lol)
I looked at the Peter method and, Im really dumb to didnt tough about
defining a pattern like *_v001.0001.exr * like this, it sort me only one
frame...which is perfect and less memory consuming I guess.
And glob use seems to be perfect for what I want to do ! so thank you to
point me in this direction :p
I tried also the Peter code, and it give me a good listing of my element
like I wanted:
HPO7_SEQ004_031_VDMRoom_ALB
HPO7_SEQ004_031_VDMRoom_AMB
HPO7_SEQ004_031_VDMRoom_BTY
HPO7_SEQ004_031_VDMRoom_Cutouts_ALB
HPO7_SEQ004_031_VDMRoom_Cutouts_AMB
HPO7_SEQ004_031_VDMRoom_Cutouts_DET
HPO7_SEQ004_031_VDMRoom_DET
HPO7_SEQ004_031_VDMRoom_DIF
HPO7_SEQ004_031_VDMRoom_DPF
HPO7_SEQ004_031_VDMRoom_Decals_ALB
HPO7_SEQ004_031_VDM_ALB
HPO7_SEQ004_031_VDM_AMB
HPO7_SEQ004_031_VDM_BTY
HPO7_SEQ004_031_VDM_DIF
HPO7_SEQ004_031_VDM_DPF
HPO7_SEQ004_031_VDM_Fresnel_mat
Unfortunatly, a new problem come to me, I looking to get that kind of list:
HPO7_SEQ004_031_VDMRoom
HPO7_SEQ004_031_VDMRoom
HPO7_SEQ004_031_VDMRoom
HPO7_SEQ004_031_VDMRoom_Cutouts
HPO7_SEQ004_031_VDMRoom_Cutouts
HPO7_SEQ004_031_VDMRoom_Cutouts
Right now, Im looking the documentation to find a way to do it, Im thinking
about string methods, I also though: " hey, I just have to delete the 4 last
characters, but na ! itll not work because sometime I have something like
"_Fresnel_mat'' which is of course more than 4 chars...)
Maybe the best would be to declare something like "in the string, look at
the last "_" and delete it + whatever there is after"
but I didnt find how to do it, I mean I tried splitext which is, not
appropriate.
Do I have to declare a list of element like:
elementList: ["_ALB", "AMB", "_Beauty", etc...]
and to search that pattern in the files name to remove it after ? it seems
not bad as solution, but I pretty sure there is a better way to do it.
right ?
anyway, thank very much guys ! :)
and have a good day !

You can use glob. Assuming the files are all in one directory:
import os
import glob
folder = r"C:\log\renderfiles"
# find files that end with "_V001.0001.exr"
pattern = os.path.join(folder, "*_V001.0001.exr")
files = glob.glob(pattern)
# remove the directory
names = [os.path.basename(f) for f in files]
# remove everything after and including the last occurence of "_"
names = [n.rpartition("_")[0] for n in names]
print "\n".join(sorted(names))

Path / Listing and os.walk problem.
Hi So here is my problem: I have my render files that are into a directory like this: c:\log\renderfiles\HPO7_SEQ004_031_VDM_DIF_V001.0001.exr c:\log\renderfiles\HPO7_SEQ004_031_VDM_DIF_V001.0002.exr c:\log\renderfiles\HPO7_SEQ004_031_VDM_DIF_V001.0003.exr c:\log\renderfiles\HPO7_SEQ004_031_VDM_AMB_V001.0001.exr c:\log\renderfiles\HPO7_SEQ004_031_VDM_AMB_V001.0002.exr c:\log\renderfiles\HPO7_SEQ004_031_VDM_AMB_V001.0003.exr True is, there is like 1000 Files is the directory (C:\log\renderfiles\) What Iam looking to is to extract the first part of the filenames as a list, but I dont want the script to extract it 1000times, I mean I dont need it to extract HPO7_SEQ004_031_VDM_AMB 150 times, because there is 150 Frames. (not sure if its clear tought) so far, I would like the list to look lik: ["HPO7_SEQ004_031_VDM_DIF", "HPO7_SEQ004_031_VDM_AMB", etc...] I start to think about that, to try to use a for (path, dirs, files) in os.walk(path): list.append(files) but this kind of thing will just append the whole 1000 files, thing that I dont want, and more complicated I dont want the thing after "AMB" or "DIF" in the name files to follow. (thing I can delete using a split, if I read well ?) I trying to search on internet for answer, but seems I find nothing about it. Someone can help me with that please, show me the way or something ? Thank you ! :) -- http://mail.python.org/mailman/listinfo/python-list
