In this problem, you will implement a transposition cipher that, instead of dividing the original text into odd and even characters, separates it into three sets of characters. As an example, we will use this 1977 quote by Digital Equipment Corp. president Ken Olson -- "There is no reason anyone would want a computer in their home." (Spaces are represented with the square u-like character.) There is no reason anyone would want a computer in their home. Rail 1: T r S d i t i h a C. e Rail 2: e a u a u in h Rail 3: a W n. m m Example three-rail transposition. The resulting encrypted text is produced by reading the text horizontally, i.e., adding the three rails: Rail 1 + Rail 2 + Rail 3 = **“Trinrs yeoda cpeitihehesoeoao u naournhro.e annnwlwt mt e m" (without the quotes). Requirements: Implement the three-rail transposition cipher above, placing your code in the file p4_2.py (template I provided, replace comment at the beginning of the file with your own code). Feel free to develop your…
