In Python 3, Please and thank you!

Write a dictionary 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 a symbol %, and so forth. The program should implement a function to input a sentence, then use the dictionary to write an encrypted version of the input and display it. Write a second function that takes the encrypted text and displays its decrypted contents
