Your Task

In this assignment, you will design and implement a word printing program for the client that

allows users to input a valid word, then the program will print the word in a n x $5($n columns

x $5$ rows$)$ grid.

Functional Requirements

The program should be implemented in Python. The client has specified the following

requirements for the functionality of the program:

$1.$ The program should be running without errors throughout two Phases: Information

Gathering and Information Presenting.

$2.$ Information Gathering is to gather the information from users such as a valid word

$($valid inputs: any single word only including letters $$C$,$A$,$T$,$D$,$O$$ and $$G$,$

one letter can appear more than once in the word, case insensitive$)$ and a break$-$word

to break the iteration $($valid inputs: $$END$,$ case sensitive$).$

$3.$ If the user enters nothing or invalid input $($e$.$g$.,12,5\mathrm{.}8$ or $$abc$),$ the program

should alert an error message by a print function and then ask the user to re$-$enter. The

process should iterate until a valid input is entered.

Figure $1$: Part of valid words in n x $5$ grid

$4.$ Information Presenting is to present the outcome. Once receiving a new valid word

from users, the program should print the word in a n x $5$ grid $($one word each time,

one space between different letters. For example, each letter is presented in a $5$ x $5$

grid. A word with three letters will be in a $15$ x $5$ grid as Figure $1.$ No extra space

between the two letters$).$

$5.$ The program will continue to ask the user to enter a word until the break$-$word $$END$$

is entered as the input and the program stops.

$6.$ The word presented in the n x $5$ grid should be the same as the letter$/$word in Figure $1$

$($pay attention to the index value for each $*).$ Do not show the table and index

number. Just show the word using $*.$

$7.$ The code for the word should be organized efficiently with iterations and conditionals

as the sample solution of Practice $3$ question b$2.$ Just printing the word one line by

one line using print $(***)$ is not acceptable.
