Day 7: „Save our Souls“ – we build a Morse Code Generator

Not only a Morse Code Generator but we also allow the user to store his morse code into a txt-file – if he asks nicely.

 

The terminal output looks like this

 

 

The saved file looks like this:

 

 

This program takes the topic of yesterday „Dictionaries“ to a new level, since the Morse Code is saved in a dictionary.

 

This is the program. We have two functions: One generates the code and the other handles the writing and saving to a file.

 

from morse_dictionary import morse # this is where the morse dictionary is stored

# we give the user the chance to save their morse code to a text file
def save_txt(txt_morse):
    if (input("Do you want to save your text to a file? (y/n)")=="y"):
        filename = input("Give the file a name: ")
        
        if (filename==""): # if user enters no file name we called it "morse.txt" by default
            filename = "morse"
            
        file = open(filename+".txt","w") #opens or creates a txt-file
        file.write(txt_morse) # write the morse code to the file
        file.close() # close the file again

# the function takes in the plain text and converts it to morse code with the morse dictionary        
def morse_gen(text):
    txt_upper = text.upper() # since our dictionary only undertands capital letters
    txt_morse = ""
    for x in (txt_upper):
        # we get the morse code for every letter and add it to txt_morse
        # we also include two spaces after every letter to make the formatting clearer
        txt_morse += morse.get(x, x) + "  " 

    print(txt_morse)   # print the morse code
     
    save_txt(txt_morse) # call the save to file function
    
    if (input("Do you want to enter another message? (y/n)")=="y"):
        morse_gen(input("Enter the sentence you want to translate (A-Z,a-z,0-9): "))
    else:
        raise SystemExit #proper program exit
    
    
    
print("*****************************************")
print("**** Morse Code Generator 1912 Model ****")
print("*****************************************")
morse_gen(input("Enter the sentence you want to translate (A-Z,a-z,0-9): "))

This is the Morse Dictionary:
