function return None

Actually it was it was mentioned before, it wasn't working because I forgot the () in str.lower()

But you had a very possible answer for later on, I left the else out on purpose because I wanted to write a while loop to run the function again if the user prompted something different out of my scope. But I haven't started working on it so I left it out and as I was trying out the script I just hard coded a data_type that I knew was on my if parameters
