2 solutions solution in Clear category for Morse Decoder by donnythelegend

def morse_decoder(code):
## Solution 1: The long way.
## Split code into words using triple whitespace.
#words = code.split(' ')
## Initialize empty object for letters.
#letters = None
## Initialize decode string.
#decode = ''
## Loop through words.
#for w in words:
# # Point letters to new list from split word.
# letters = w.split()
# # Loop through letters.
# for l in letters:
# # Add MORSE value with key l to decode.
# decode += MORSE[l]
# # Add a whitespace to decode after the full word has been translated.
# decode += ' '
# Return decode with removed final whitespace and first character capitalized.
#return decode[:-1].capitalize()
# Solution 2: One liner.
# This line splits code into words, splits the words into letters,
# joins the translated letters together, joins the translated words with whitespaces,
# then capitalizes the first character of the result.
return ' '.join(''.join(MORSE[letter] for letter in word.split()) for word in code.split(' ')).capitalize()
