You Learn by Doing

 I had an entirely different vision of how my Learn and Review screen displays would look. 

But over time, something else, something more workable emerged.

More to the point, below is a screen capture of a practice session based on a Tech with Tim (TwT) tutorial on YouTube entitled, "10 Python Comprehensions You SHOULD Be Using" (here)

It is but one of a number of practice sessions in a test Py file. So it gets an identifying frame ID (009 in this case).

It gets a heading banner (Green box characters in this example)
Each subsection gets its own ID, for example: (9a), (9a'), (9b), (9c), etc.

Moreover, at subsection (9_), I insert in my own words, a summary of what I understand after having tried some to TwT's 10 lessons.

While not shown in the below example, I also denote in later lessons, the time stamp for where the lesson occurs in TwT's tutorial.
(BTW, left click on below image to see it bigger) 

Below is another screen grab showing the TwT time stamps with the try-it-out runs
