File encryption and decryption write a program that uses a dictionary to assign "codes" to each letter of the alphabet. for example: codes = { βaβ : β%β, βaβ : β9β, βbβ : β@β, βbβ : β#β, 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, then use the dictionary to write an encrypted version of the fileβs 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.
