Program language is Python.

File Encryption and Decryption Write a program that uses a dictionary to assign "codes" to each letter of the alphabet. For example codes ={ A' : '8', a' : '9,, 'B, : e", '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 e, 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 decryptedcontents on the screen
