Question

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 a Morse code and have it converted back to the original message. The encoding of Morse code is given below.

Answer 1

Answer:

#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

         #corresponding 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 indicated 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:

 

        #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

     #driver function to run the program

     def main():

       message="Lalchand Mail"

       result=encrypt(message.upper())

       print('Morse Code of ' message.upper(),':'result)

      #excutes the main function

      if__name__=='__main__':

process finishes with exit code 0
