How do I make my Caeser Cipher work?

This is what I have so far for my Caeser Cipher program.

 import string
    character = []
    message = raw_input('What is your message? ').lower()
    shift = raw_input('What is your shift key? ')
    code = raw_input('Would you like to cipher(c) or decipher(d)? ')
    if str(code) == 'd':
        for character in message:
            number = ord(character) - int(shift)
            if number <= 96:
                number = ord(character) + 26 - int(shift)
            character = chr(number)
    elif str(code) == 'c':
        for character in message:
            number = ord(character) + int (shift)
            if number >= 123:
                number = ord(character) - 26 + int(shift)
            character = chr(number)
    print(str(character))

Every time I use this program, I get back the encrypted or decrypted message of only the last letter of the line I type for the message. I'm not sure how to print my entire encrypted or decrypted message out.

The problem is that you only print once outside the for loop.

You can move the print statement inside the for loop.

if str(code) == 'd':
    for character in message:
        number = ord(character) - int(shift)
        if number <= 96: 
            number = ord(character) + 26 - int(shift)
        character = chr(number)
        print( str(character))
elif str(code) == 'c':
    for character in message:
        number = ord(character) + int (shift)
        if number >= 123:
            number = ord(character) - 26 + int(shift)
        character = chr(number)
        print(str(character))
