i'm renaming a batch of files i downloaded from a torrent and wanted to get the episode's name,so i figured regex would do the trick. I'm kinda new to regex so I'd appreciate the help. This is what i could come up to:

i have a class related to other renaming functions so the function defined here is within this class, that initializes with the path to the files directory, the expression to rename to and the file extension.

im using glob to access all files with the extension ".mkv"

for debugging i printed out all the file names:

Mr.Robot.S02E01.eps2.0_unm4sk-pt1.tc.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E02.eps2.0_unm4sk-pt2.tc.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E03.eps2.1_k3rnel-pan1c.ksd.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E04.eps2.2_init_1.asec.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E05.eps2.3.logic-b0mb.hc.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E07.eps2.5_h4ndshake.sme.720p.WEB-DL.x264-[MULVAcoded].mkv

Mr.Robot.S02E12.eps2.9_pyth0n-pt2.p7z.720p.WEB-DL.x264-[MULVAcoded].mkv









def strip_ep_name(self):

    for i, f in enumerate(self.files):

        f_list = f.split("\")

        name, ext = os.path.splitext(f_list[-1])

        ep_name = name.strip(r'(.*?)".720p.WEB-DL.x264-[MULVAcoded]"')

        print(ep_name)

for me, the goal is to get the episode's name, either with or without the episode's number, because i can, later on, give the episode a new name.

and the output is:

r.Robot.S02E01.eps2.0_unm4sk-pt1.t

r.Robot.S02E02.eps2.0_unm4sk-pt2.t

r.Robot.S02E03.eps2.1_k3rnel-pan1c.ks

r.Robot.S02E11.eps2.9_pyth0n-pt1.p7z

r.Robot.S02E12.eps2.9_pyth0n-pt2.p7z

I wanted to strip all the ".eps2.2" before the episode's name, but they dont follow an order.

Now I don't know how to move on from here. can anyone help?

Do it all in one step:

.epsd+.d+[-_.](.+?)(?:.720p.+).(w+)$

Broken down, this reads:

.epsd+.d+ # ".eps", followed by digits, a dot and other digits

[-_.]         # one of -, _ or .

(.+?)         # anything else lazily afterwards

(?:.720p.+)  # until .720p is found (might need some tweaking)

.            # a dot

(w+)$        # some word characters (aka the file extension) at the end

This needs to be replaced by .1.2 to get your desired format in the end.

import re

See a demo on regex101.com.

Firstly import the regex module of Python:

import re

Then use this to replace from "r.Robot.S02E01.eps2.0_unm4sk-pt1.t" :

ep_name = re.sub(r"eps2.d{1,2}(.|_)","",episode_name)

use ep_name in loop and pass episode name to episode_name one by one and then print ep_name.

Output will be like:

r.Robot.S02E01.unm4sk-pt1.t

I'm not sure if I understand correctly, I don't know the series hence nor do I the titles. But do you really need re?

for f in files:

    print(f[23:-35].split('.')[0])

results in

unm4sk-pt1

unm4sk-pt2

k3rnel-pan1c

init_5

pyth0n-pt2      

Edit:

I still don't see an actual target format definition in your post, but just in case that @Jan is right, here's the re-less solution for that, too:

for f in files:

    print(f[:16] + '.'.join(f[23:].split('.')[:2]) + '.mkv')
