Morse Decoder - Ex094 - 04-18-2013

This is a very simple python program that uses a dictionary containing Morse code key like '-' for T. The condition to decode via key present in the dictionary is:

Code:
store = ''
for items in code:
    if the key is in the dictionary:
        then store the value of the key in the variable Store
    if else the key is not found in the dictionary:
        print that the key was not found

print value of the variable store

Source Code:

Code:
morse = {'.-' : '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', '-----' : '0', '.----':'1','..---':'2','...--':'3','....-':'4','.....':'5','-....':'6','--...':'7','---..':'8','----.':'9',}

store = ''

# We need to store the code with the spaces in between as intact so we use split() to keep the spaces between the codes and make a list code.
code = input('Input your Morse Code: ').split()

#For Error management
try:

#For each item in the list 'code'
	for item in code:

#Get the value of the key and store it in the variable 'store', if the key exists in the dictionary, if not morse[item]
#will be false and it will raise the KeyError that key not found in the dictionary which will be handled
#as a normal error at the end of the code.
		store = store + morse[item]

#Prints the decoded code stored in the variable 'store'
	print('Your Decoded Message is: %s' % store) 

# In case of the above code returns false due to morse[item]
except KeyError as error:

#Display error
	print('Your code contains invalid morse code character', error)

Everything is explained in the code comments, Have fun!
If you like, you can make it encode the normal text into a morse, you just need to reverse the dictionary values and then ask for normal text Smile

Well done, @Ex094.
I thought lately that we could make a multi encoder for HC that includes morse code as well.

RE: Morse Decoder - Psycho_Coder - 04-18-2013

Wow that looks good , I think I am going to make one in C++ or in VB.NET too . Seeing this I remembered Coder-sans contest in which we were given a morse code for decoding ..

Really great job! I like that you are still making tools in Python. And you did a very great job at explaining that code also.

RE: Morse Decoder - Coder-san - 04-18-2013

Nice. A job well done.
