Question

Morse Code Encryption/Decryption Program - Develop and test a Python program that allows a user to type in a message and have it converted into Morse code, and also enter Morse code and have it converted back to the original message.

Answer 1

Code:

#dict of morse code
morse_code_dict = { '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':'--..',
                    '1':'.----', '2':'..---', '3':'...--',
                    '4':'....-', '5':'.....', '6':'-....',
                    '7':'--...', '8':'---..', '9':'----.',
                    '0':'-----', ', ':'--..--', '.':'.-.-.-',
                    '?':'..--..', '/':'-..-.', '-':'-....-',
                    '(':'-.--.', ')':'-.--.-'}

#function to convert text to morse code
def to_morse_code():
    text=input("Enter messege to convert: ")
    text=text.upper()
    morse_code = ''
    for letter in text:
        if letter != ' ':

      
            morse_code += morse_code_dict[letter] + ' '
        else:
    #it will maintain the spaces
            morse_code += ' '

    return morse_code

#function to conver the morse code to text
def morse_to_text():
    code=input("Enter the code: ")

    code += ' '

    text = ''
    text1 = ''
    for letter in code:

        # if there any spaces
        if (letter != ' '):
            #it counts the spaces
            i = 0

            #it store the morse code of single character
            text1 += letter

        # in case of space
        else:
            # if i = 1 that indicates a new character
            i += 1

            # if i = 2 that indicates a new word
            if i == 2 :

                 # adding space to separate words
                text += ' '
            else:

                #it will access the keys using their values
                text += list(morse_code_dict.keys())[list(morse_code_dict.values()).index(text1)]
                text1 = ''

    return text

to_morse_code()

morse_to_text()
