All uppercasse is usually used to indicate a constant value. Also the second line indent is wrong, so it should look like: CONFIGFILE = raw_input("Enter config location: ") while CONFIGFILE == "": CONFIGFILE = raw_input("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 There are various ways to do that, the best solution is to use curses, but thats a steep lrearning curve. An easier way is just not to print the line inside the loop, like this: CONFIGFILE = raw_input("Enter config location: ") if not ConfigFile: print "You must enter configuration file location: " while CONFIGFILE == "": CONFIGFILE = raw_input() However that will still scroll the line up the screen, not so pretty. The next simplest solution is to use sys.stdout/sys.stdin to access the input/output buffers directly. This will allow you to read the input directly including the newline character and to write control codes to stdout to erase p[revious characters etc. But this gets messy quickly. Which takes us back to curses (assuming you are on Linux!) or the msvcrt module if you are on Windows. Both of these have a getch function to read characters one by one and allows you to process them. No easy solutions, but several ways to do it depending on your needs and enthusiasm levels. -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
