Question

Write a Python program that reads from the keyboard a word and displays the encrypted version of that word. Assume that only the characters (A, D, I, R, Y ) are allowed in the input word and that the encoding is as shown in the following table:

For example the word RIYAID will be encoded as BATMAN.

You need to use three functions, readWord(), encrypt() and displayEncryption().

• readWord() is called by main() to read from the keyboard 6 characters.

• encrypt() is called by main() to convert the characters obtained from readWord() into corresponding encryptions as indicated in the table.

• displayEncryption() is called by main() to display the encrypted word on the screen.

Notes:

1. Your program should check the validity of the user input.

Explanation / Answer

I think the code is self explanatory but still i would explain what i have done. For encryption i have created a dictionary which will map every charachter with the associated value.

Before running any function i am checking if the user provided any input or not if no input then i am displaying a message to provide input.

In readWord() function i am using input function to get the input from user keyboard.

In encrypt() function i am first converting the input to upper case so that upper and lower case letters is able to treated properly. I convert the input into a list using list function and then iterate over the list to convert every character to the encrypted one using get method of dictionary. Once the encryption is done i convert it into string using ''.join function.

In displayEncryption() function i am simply displaying the output on screen using print() function.

Also i have taken care of the fact that if there is any word that does not follow encryption my program will print it as is.
