Ok, I will keep that in mind. After reading from http://docs.python.org/library/stdtypes.html I came up with this: from sys import argv script, filename = argv print "We're going to erase %r." % filename print "If you don't want that, hit CTRL-C (^C)." print "If you do want that, hit RETURN." raw_input("?") print "Opening the file..." target = open(filename, 'w') print "Truncating the file. Goodbye!" target.truncate() print "Now I'm going to ask you for three lines." line1 = raw_input("line 1: ") line2 = raw_input("line 2: ") line3 = raw_input("line 3: ") print "I'm going to write these to the file." bag = "%s\n%s\n%s\n".format(line1,line2,line3) target.write(bag) print "And finally, we close it." target.close() Is this how it is supposed to look like using str.format?
