Goodbye!") target.truncate() print("Now I am going to ask for three lines.") line1 = input("line 1: ") line2 = input("line 2: ") line3 = input("line 3: ") print("I am 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.") target.close()
