I recently discovered Colaboratory. After playing with it for a few minutes, I have some idea what "playground mode" is - that no output is saved in that mode, but couldn't find a formal note in the FAQ or other help material (intro notebook) that I located. I'm wondering if there are more details to know about this mode and when is it suggested to be used?
Thanks.
Playground mode opens an ephemeral copy of the notebook that isn't saved.
Typical uses include:
Without playground mode, these tasks would require creating a copy of the notebook in Drive, which clutters the file list a bit. (Of couse, you can always save a copy of the notebook after opening in playground mode if needed.)
