# extra credit
#    Get rid of the part from line 10-15 where you use raw_input and try the script then.
#    Use only raw_input and try the script that way. Think of why one way of getting the filename would be better than another.
#    Run pydoc file and scroll down until you see the read() command (method/function). See all the other ones you can use? Skip the ones that have __ (two underscores) in front because those are junk. Try some of the other commands.
#    Startup python again and use open from the prompt. Notice how you can open files and run read on them right there?
#    Have your script also do a close() on the txt and txt_again variables. It's important to close files when you are done with them.
