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."
 
target.write(line1)
target.write("\n")
target.write(line2)
target.write("\n")
target.write(line3)
target.write("\n")
 
print "And finally, we close it."
