kyu_3.rail_fence_cipher_encoding_and_decoding.encoding_and_decoding module

kyu_3.rail_fence_cipher_encoding_and_decoding.encoding_and_decoding.decode_rail_fence_cipher(string: str, n: int) → str[source]

Function/method that takes 2 arguments, an encoded string and the number of rails, and returns the DECODED string.

Parameters

  • string – an encoded string

  • n – the number of rails

Returns

the DECODED string

kyu_3.rail_fence_cipher_encoding_and_decoding.encoding_and_decoding.encode_rail_fence_cipher(string: str, n: int) → str[source]

This cipher is used to encode a string by placing each character successively in a diagonal along a set of “rails”. First start off moving diagonally and down. When you reach the bottom, reverse direction and move diagonally and up until you reach the top rail. Continue until you reach the end of the string. Each “rail” is then read left to right to derive the encoded string.

Parameters

  • string – a string

  • n – the number of rails

Returns

the ENCODED string

kyu_3.rail_fence_cipher_encoding_and_decoding.encoding_and_decoding.get_rails(string: str, n: int) → list[source]

Create rails matrix.

Parameters

  • string – a string

  • n – the number of rails

Returns

rails matrix
