Question 9: Write a function decipher_code() that takes a string as its argument and returns a string. The function will process each sentence at a time (sentences are limited with a full-stop '.'). Each sentence will be converted to a list by string2list, then processed by flip-list to be deciphered into a meaningful text, then converted back to a string by list2string. The function will return all the deciphered sentences into one single string. Note: (1) For testing, it is guaranteed that the lengths of input strings are square numbers. 5 Example 1: H By Example 2: flip list у H B 1 2 flip list 2 4 3 4 1 3 Figure 3: Examples showing 2D lists before and after calling flip_list() function >>>decipher_code('BlHyoee 1') 'Hello Bye' >>>secret 'ttuo YrAtwoin L AundibKgSson.roelf ad YfImPAoitmr ucleoGAisrgora O' >>>decipher.code(secret) 'You Know About List And String. It Is Official You Are A Good Programmer' (2) Some sentences might be not valid (having numbers or special characters), they will then be ignored. Question 6: Write a function horizontal-flip that takes a 2D square list (a list that has an equal number of rows and columns) as its argument and flips the list horizontally. The function returns nothing and should modify the input list directly (see Fig 1). You will assume that the input list is a valid 2D square list containing any character or number. You must use nested for loops. >>>input_list = [['B', 'I', 'H'], ['y', 'o', 'e'], ['e', '', '1']] >>>horizontal.flip(input_list) >>>input_list [['H', 'I', 'B'], ['e', '0', 'y'], ['1', '', 'e']] Example 1: H Horizontal flip B у у B Example 2: Horizontal flip 3 4 3 Figure 1: Examples showing 2D lists before and after calling horizontal-flip() function Question 7: Write a function transpose that takes a 2D square list (a list that has an equal number of rows and columns) as its argument and transposes the list. Transposing the list will flip it over its diagonal. The function returns nothing and should modify the input list directly (see Fig. 2). You will assume that the input list is a valid 2D square list containing any character or number. You must use nested for loops. 4 Note: The transpose of a list A is the list B defined by making the first row of A the first column of B, the second row of A the second column of B, etc. In other words, when taking a transpose, the rows and columns are interchanged. See this link for an animation (Source: https://linearalgebra.math.umanitoba.ca) >>>input_list = [['H', 'I', 'B'], ['e', 'o', 'y'], ['1', '', 'e']] >>>transpose(input_list) >>>input_list [['H', 'e', '1'], ['I', '0', ''], ['B', 'y', 'e']] Example 1: H H Transpose y B Example 2: Transpose 1 Figure 2: Examples showing 2D lists before and after calling transpose() function Question 8: >>>input_list = [['B', 'I', 'H'], ['y', 'o', 'e'], ['e', '', '1']] >>>flip_list(input_list) >>>input_list [['H', 'e', '1'], ['I', '0', ''], ['B', 'y', 'e']] Write a function flip_list that takes a 2D square list as its argument and returns nothing. This function transforms the 2D list by changing the position of its items as shown in the example below. You will have to use the two previous functions (see Fig. 3). You will assume that the input list is a valid 2D square list containing any character or number.
