bencode / bdecode

Created by Julien Palard

Instructions

Expose two functions bencode and bdecode.

  • bencode take one object as a parameter and returns bytes.
  • bdecode take bytes as a parameter and returns an object.

objects may be of type:

  • str
  • int
  • list
  • dict

You have to follow the bencode encoding and decoding algorithm, see Wikipedia bencode page. You'll have to encode and decode strings, use "UTF-8" everywhere and explicitly.

Hints

You may code other helper functions in your module, functions to help bencode and bdecode in their work. You also can store module variables and use them but only for you to use.
