Section 4.5.3 suggested change

[srw2k]

In Section 4.5.3, the output for the 5th code cell is ['red', 'green', 'blue', 'purple'], but shouldn't it be ['red', 'green', 'blue', 'purple', 'purple'] instead? The sentence immediately below seems problematic, too, and perhaps should read:

Notice that my_list contains “purple” twice, even though the code above only adds it once.

Ah, yes, that is a byproduct of using the Jupyter plugin for sphinx. It actually runs the code when we build the book... Good, 99% of the time, as it makes sure the results are actually what the code produces. But of course there is no way to tell it to run a cell twice.

We should redo this example another way.

I see, makes sense. BTW, this same issue appears in Section 5.2.2.
