Python Programming, I need someone to edit my code. Very easy.

Write a fx'n called secret that takes a string & a key [integer]. The fx'n ciphers the string into a different string & returns the new string. Please be aware that when we reach "z", we must 'roll' into the alphabet once more. Therefore, ord('z')+4 should give us ord('d') (from above example)

When running the code, I get: But the output screenshot shows different results. Decrypted message should be what the user input for message. "zxywv" doesn't equal "sqrpo" and "z" doesn't equal "s"

#Stored all the letters in order to reduce computation letters = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"]

def cipher(message,key): encrypted_message = "" for i in message: #Bringing the encrypted value in the range of 0 to 25 to get proper letter encrypted_message += letters[((ord(i)+key)%97)%26] return encrypted_message

def decipher(message,key): decrypted_message = "" for i in message: decrypted_message += letters[((ord(i)-key)%97)%26] return decrypted_message

#Taking Inputs message = input("Enter the Meassage : ") key = int(input("Enter an Ineger Key : "))

#Printing the messages

print("Encrypted Message : ",cipher(message,key))

encrypted_message = cipher(message,key) print("Decrypted Mesage : ",decipher(encrypted_message,key))
