The function under test uses code like this To be sure this will work, I created a stat attribute. But what if we wanted to return every line in the file, properly separated.

The output of the code is that earlier file is appended with new data. These files, known as scripts, are programs you can execute from either the operating system prompt or by creating a script tool that executes the script.

This directory is used in subsequent steps. Info button to display and clear. To start a new line after you write data to the file, you can add an EOL character.
