A) Write a program that uses a dictionary to assign \"codes\" to each letter of the alphabet. For example:
codes = { 'A': '%', 'a': '9', 'B': '@', 'b': '#', etc...}
Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth.
The program should open a specified text file, read its contents, and then use the dictionary to write an encrypted version of the file's contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file.
Write a second program that opens an encrypted file and displays its decrypted contents on the screen.
