Morse Code Converter

This script takes in a string, and outputs morse code.

The alphabet is a dictionary of key value pairs, associating each character to the morse code signal. It prints out the phrase in morse code. Letters are folowed by a space, words followed by two spaces. If an incompatible character is entered, it represented with an 'e'.

alphabet = {'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':'-----'
            }

    # Read word, convert to upper case string
    word: str = input('Please enter the word: ')
    word = word = str(word).upper()

    # List for morse characters
