Program in python 3.x. Please add comments in order to increase understanding of the solution. (If possible try to make the code as simple as possible). Thanks

Morse Code uses a series of short and long pulses called dots and dashes, respec tively, to encode letters and digits. For example, the letter A is "dot-dash," B is "dash-dot-dot-dot." Find a table of Morse Code on the Internet to create a dictionary for mapping characters and digits to Morse Code. Use the dictionary to create a program that can translate between Morse Code and characters and digits.

Explanation / Answer

Python program to implement Morse Code Translator ''' VARIABLE KEY 'cipher' -> 'stores the morse translated form of the english string' 'decipher' -> 'stores the english translated form of the morse string' 'citext' -> 'stores morse code of a single character' 'i' -> 'keeps count of the spaces between morse characters' 'message' -> 'stores the string to be encoded or decoded' ''' # Dictionary representing the morse code chart 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 encrypt the string # according to the morse code chart def encrypt(message): cipher = '' for letter in message: if letter != ' ': # Looks up the dictionary and adds the # correspponding morse code # along with a space to separate # morse codes for different characters cipher += MORSE_CODE_DICT[letter] + ' ' else: # 1 space indicates different characters # and 2 indicates different words cipher += ' ' return cipher # Function to decrypt the string # from morse to english def decrypt(message): # extra space added at the end to access the # last morse code message += ' ' decipher = '' citext = '' for letter in message: # checks for space if (letter != ' '): # counter to keep track of space i = 0 # storing morse code of a single character citext += 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 decipher += ' ' else: # accessing the keys using their values (reverse of encryption) decipher += list(MORSE_CODE_DICT.keys())[list(MORSE_CODE_DICT .values()).index(citext)] citext = '' return decipher # Hard-coded driver function to run the program def main(): message = "GEEKS-FOR-GEEKS" result = encrypt(message.upper()) print (result) message = "--. . . -.- ... -....- ..-. --- .-. -....- --. . . -.- ... " result = decrypt(message) print (result) # Executes the main function if __name__ == '__main__': main()

If you feel problem then don't see the encryption massage part starting point and last one ....
