Create a program that will encrypt letters and create a secret code.  You will create an array of numbers from 0 - 25. use [i for i in range (26)] to create an array of numbers from 0 - 25. use random.shuffle to to shuffle the above array.  This will be used for a new letter index order.   For example:  The first created array [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25] gets shuffled to become [2, 14, 12, 20, 16, 5, 11, 1, 13, 17, 15, 21, 19, 10, 23, 22, 25, 3, 6, 7, 18, 4, 9, 24, 0, 8] This will be used as the new index for the encrypted alphabet.   create an array of letters using list(string.ascii_lowercase), this requires importing  the string module.   This will create: ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'] Accept an input of a word.  Using the above tables take each letter of the word and convert it to the encrypted letter.   Print each letter with the existing letter value and the encrypted letter value.   Print the newly encrypted word.   Sample output: >>> enter string to encrypt: congratulations c 2 11 o 14 9 n 13 5 g 6 24 r 17 7 a 0 15 t 19 17 u 20 1 l 11 23 a 0 15 t 19 17 i 8 0 o 14 9 n 13 5 s 18 16 ljfyhprbxprajfq >>>

Question

Create a program that will encrypt letters and create a secret code.  You will

create an array of numbers from 0 - 25.

use [i for i in range (26)] to create an array of numbers from 0 - 25.

use random.shuffle to to shuffle the above array.  This will be used for a new letter index order.  

For example: 

The first created array

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]

gets shuffled to become
[2, 14, 12, 20, 16, 5, 11, 1, 13, 17, 15, 21, 19, 10, 23, 22, 25, 3, 6, 7, 18, 4, 9, 24, 0, 8]

This will be used as the new index for the encrypted alphabet.  

create an array of letters using list(string.ascii_lowercase), this requires importing  the string module.  

This will create:

['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

Accept an input of a word.  Using the above tables take each letter of the word and convert it to the encrypted letter.  

Print each letter with the existing letter value and the encrypted letter value.  

Print the newly encrypted word.

 

Sample output:

>>>

enter string to encrypt: congratulations
c 2 11
o 14 9
n 13 5
g 6 24
r 17 7
a 0 15
t 19 17
u 20 1
l 11 23
a 0 15
t 19 17
i 8 0
o 14 9
n 13 5
s 18 16

Extra credit include a space as an encrypted character and allow for multiple words.
