How to Write a Morse Code Translator in Python?

Are you looking for how to write a Morse Code Translator in Python in 2023? Here in this blog, we will discuss this in detail.

What is Morse Code And How Does It Work?

The Morse code method uses pairs of dots and dashes, sometimes dits and dahs, to represent letters, numbers, punctuation, and other symbols. It was first created in the early 19th century for telegraph communications before being modified for other communication mediums, including radio.

The dots and dashes allocated to each letter, number, punctuation mark, and symbol are different. The messages are communicated by switching the signal on and off in the correct pattern. The recipient can then reconstruct the original text message from the string of dots and dashes.

Although it has been mostly overtaken by more contemporary modes of communication, morse code is still used today in some areas, such as aviation and military communications. As a technique to study the fundamentals of coding and communication, it is still a significant part of history and is still taught in many institutions of higher learning.

How does Morse code Translator Work?

A Morse code translator converts letters, numbers, and other symbols into dots and dashes (dits and dahs), and vice versa. The process typically involves the following steps:

Encoding:

The user inputs a message in plain text (for example, “HELLO WORLD”). The Morse code translator then converts each letter, number, and symbol in the message into its corresponding sequence of dots and dashes.

Transmission:

The encoded message is then transmitted by turning a signal on and off in the corresponding pattern of dots and dashes. In the case of a telegraph, this would be done by pressing a key that sends an electrical signal over a wire. In the case of radio transmission, this would be done by modulating a carrier wave with the Morse code signal.

Decoding:

The transmission receiver then decodes the message by converting the dots and dashes into the original text. This is done by looking up the unique pattern of dots and dashes in a Morse code chart and determining the corresponding letter, number, or symbol.

Output:

The decoded message is displayed to the user in plain text.

In modern times, Morse code translators are often implemented as computer software or mobile apps, which automate the encoding, transmission, decoding, and output process. These tools typically include a user interface that allows the user to input a message in plain text and a display that shows the encoded and decoded messages.

Make a Morse Code Translator in Python – Method One

Here is a basic example of how you could write a Morse code translator in Python:

# Define a dictionary to store the 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':'-----', ', ':'--..--', '.':'.-.-.-', 
                    '?':'..--..', '/':'-..-.', '-':'-....-', 
                    '(':'-.--.', ')':'-.--.-'} 

# Define a function to encode text to Morse code
def text_to_morse(text):
    morse = []
    for char in text:
        char = char.upper()
        if char in MORSE_CODE_DICT:
            morse.append(MORSE_CODE_DICT[char])
    return ' '.join(morse)

# Define a function to decode Morse code to text
def morse_to_text(morse):
    text = []
    for code in morse.split():
        for char, code in MORSE_CODE_DICT.items():
            if code == morse_code:
                text.append(char)
    return ''.join(text)

# Test the functions with a sample input
text = "HELLO WORLD"
morse = text_to_morse(text)
print("Text:", text)
print("Morse:", morse)

text = morse_to_text(morse)
print("Morse:", morse)
print("Text:", text)

This code defines two functions, ‘text_to_morse’ and ‘morse_to_text’, which encode text to Morse code and decode Morse code to text. The functions use the MORSE_CODE_DICT dictionary to look up the corresponding code for each letter, number, or symbol. The functions also handle uppercasing the input and adding spaces between words in the Morse code output. The code is then tested with sample input, “HELLO WORLD”, to demonstrate the encoding and decoding process.

Write a Morse Code Translator in Python – Method Two

Here’s another implementation of a Morse code translator in Python, using a different approach:

def text_to_morse(text):
    morse_code = {
        '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': '-----',
        ' ': ' '
    }

    morse_text = ''
    for char in text:
        char = char.upper()
        if char in morse_code:
            morse_text += morse_code[char] + ' '
    
    return morse_text

def morse_to_text(morse):
    morse_code = {
        '.-': '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',
        ' ': ' '
    }

    text = ''
    morse_chars = morse.split()
    for char in morse_chars:
        if char in morse_code:
            text += morse_code[char]
    
    return text

text = "HELLO WORLD"
morse = text_to_morse(text)
print("Text:", text)
print("Morse:", mor
