Python

3. File Encryption and Decryption Write a program that uses a dictionary to assign "codes to each letter of the alphabet. For example: codes = { 'A' ' : '9', '3' : '@', 'b' : '#', etc...) Using this example, the letter A would be assigned the symbol 3, 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
