Write a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example:

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, 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.

codes { 'A' : '%', 'a' '9', 'B' '@', 'b': '#', etc...}
