Intermediate Python

We add a new function called encode which takes the exact code as before but with three changes:

1. def encode(message): added to the beginning
2. The code is indented by four spaces
3. return morse_message added to the end

We then call our function with morse_message = encode(message)

letter_to_morse = {'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':'--..',
                   '0':'-----', '1':'.----', '2':'..---', '3':'...--', '4':'....-',
                   '5':'.....', '6':'-....', '7':'--...', '8':'---..', '9':'----.',
                   ' ':'/'}

message = "SOS We have hit an iceberg and need help quickly"


def encode(message):
    morse = []

    for letter in message:
        letter = letter.lower()
        morse_letter = letter_to_morse[letter]
        morse.append(morse_letter)

    morse_message = " ".join(morse)
    
    return morse_message


morse_message = encode(message)

print(f"Incoming message: {message}")
print(f"   Morse encoded: {morse_message}")

python encode.py
