This way, the output will still be available for us after you close the terminal or terminate the notebook that contains our program output. This will allow us to reuse the content later with the read() method that was covered in the previous section, Reading Files.

You will still be using the open() method to write to a file, except when it requires an extra argument to indicate how you want to access and write to the file.
