[Tutor] strategy in dealing with user input

[Robert Jackson]

I have a few lines of code as follows:

CONFIGFILE = raw_input("Enter config location: ")
    while CONFIGFILE == "":
         CONFIGFILE = raw_input("You must enter configuration file location: ")

Let's say the user hits enter past the initial raw_input request.  The user will then be in the while loop.  Any subsequent "enters" by the user will result in a brand new line that reads: "You must enter configuration file location: ".

Is there a way to clear out the CURRENT line while in the *while* loop so that even if the user hits enter a few extra times, it'll stay in the SAME line that reads "You must enter a configuration file location: " (and not fill up the screen with the same text over and over)?
