bencode

python3 bencode, support multiple encodings and read/write BT torrent file. this module support multiple data type, include bytes. so you can open a torrent file, if the field unable to decode, will treat as bytes, also you can insert bytes data. auto sort dictionary key when insert dict.

Support UTF-8

data type

example

import bencode;
>>> f = open('bt.torrent', 'rb');
>>> bt = bencode.decode(f.read(), 'encoding; default is utf-8');
>>> f.close();
>>> bt.keys();
dict_keys(['info', 'announce-list'])
>>> for i in bt['info']['files']:
    print(i['path']);

['MTKV25.zip']
>>> bt['info']['files'][0]['path'][0] = 'modify.zip';
>>> f = open('bt1.torrent', 'wb');
>>> f.write(bencode.encode(bt));
10537
>>> f.close();

or

>>> import bencode
>>> bt = bencode.load('bt.torrent', ['gbk', 'gb2312', 'big5']);
do something
>>> bencode.save(bt, 'bt.torrent');
true

or load with bencode.load(filename) return object, save with bencode.save(object, filename) return boolean;

result

only filename has been changed, open with downloader and successfully downloaded.
so i can say this module can fully support torrent file for read/write.

Good Luck
