You need to torrent.generate() before you can torrent.write(). Also, you can modify torrent.files like any regular list, so you can do stuff like del torrent.files[3] or torrent.files.remove("file/path").

Thanks for your reply. It seems that i have a wrong understanding for torf.

add torrent.generate

I tried torrent.generate() . But there are some errors. The code and error information are below:

from torf import Torrent

torrent = Torrent.read('./temp/old.torrent')
#torrent.files = [torrent.files[0], torrent.files[2], torrent.files[-1]]
del torrent.files[3]
torrent.generate()
torrent.write('./temp/new.torrent')

Traceback (most recent call last):
File "test.py", line 6, in
torrent.generate()
File "D:\work\02work\work\009torrent\rw-torrent\venv\lib\site-packages\torf_torrent.py", line 1016, in generate
raise RuntimeError('generate() called with no path specified')
RuntimeError: generate() called with no path specified

add path

I add a path to torrent:

from torf import Torrent

torrent = Torrent.read('./temp/old.torrent')
#torrent.files = [torrent.files[0], torrent.files[2], torrent.files[-1]]
del torrent.files[3]
torrent.path = 'temp'
torrent.generate()
print(torrent.files)
torrent.write('./temp/new.torrent')

But the new.torrent contains the files which are in my computer, instead of the files in the old.torrent. The information is below:

λ ls temp/
k old.torrent
(venv) admin@DESKTOP-ILNMBPV /d/work/02work/work/009torrent/rw-torrent
λ python test.py
[File('temp\k', size=95829), File('temp\old.torrent', size=95829)]
(venv) admin@DESKTOP-ILNMBPV /d/work/02work/work/009torrent/rw-torrent

what's more, if the path does not exist, the code and error information are below:

from torf import Torrent

torrent = Torrent.read('./temp/old.torrent')
#torrent.files = [torrent.files[0], torrent.files[2], torrent.files[-1]]
del torrent.files[3]
torrent.path = 'temp_not_exist'
torrent.generate()
print(torrent.files)
torrent.write('./temp/new.torrent')

Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\lib\os.py", line 350, in walk
scandir_it = scandir(top)
FileNotFoundError: [WinError 3] The system cannot find the specified path: 'temp_not_exist'

During handling of the above exception, another exception occurred:

my goal

I want to download several files in a torrent which contains a lot of files. I want to remove some files in the torrent. So can a torrent file be modified by torf?

Thanks @rndusr . So I can only download the specific files in the original torrent, instead of making a new torrent from the original torrent.
