Vigenere cipher with all printable characters python

"""
This is a very basic method for encrypting and decrypting vigenere ciphers with a given key
Includes ALL CHARACTERS within the ASCII Value range of 32-127 (All printable characters) unlike other vigenere cipher methods I've seen so far that only do uppercase/lowercase letters which is why I'm posting this
Sorry about the messy code, I'm mostly self-taught and do not have a lot of experience with Python but it works, I swear
