Question
I need python code only no output only code
Transcribed Image Text:def decode(code):
pass
= Test code
msg = 'Hello
print(f"Plain text message: (msg)")
encoded = encode(msg)
print(f"Encoded message: (encoded)")
decoded = decode(encoded)
• Expected output:
- Plain text message: Hello
= Encoded message: HbeklqIRon
- Decoded message: Hello
print(f'Decoded message: {decoded)}")
Transcribed Image Text:Write functions to encode and decode a plain text message with the algorithm below:
• The encode) function takes the original, plain text message as input, takes each of its character out and adds one random ASCII letter after it, making each one letter into two letters, and then append the two
letters to the new encoded string output.
• The decode) function takes an encoded message as input and decodes the messages by removing the random letters added during the encoding process. It only retains characters in the original message. The
output of the decode) function will be exactly the same as the original, plain text message.
Example
• Original message: Hello
• Encoded message: HbeklqIRon
• Decoded message: Hello
Note: the randomLetter) function is given to generate a random ASCII letter.
import string
import random
def randomLetter0:
return random.choice(string.ascii_letters)
def encode(message):
pass
def decode(code):
pass
# Test code
msg = 'Hello'
print(f"Plain text message: (msg)")
